Trespasser Awakening (Trespasser HD Remake) (Unreal Version)
"Between 2021 and 2022 I recreated Trespasser in Unity and spent almost all of my free time indoors on creating this game even though I was completely unfamiliar with game development and was learning Unity from ground up.
I had a lot of fun though and spent a good amount of money on 3D assets as well as different AI and Player Controllers to find the best I could. After release though, I was never happy with the graphics, and I knew that Unreal Engine could do better. I also struggled with the game's performance as I only had a 14inch laptop and so I had to set most of the trees to be rendered as 2D billboards up until a few meters of distance to the player.
In June of last year, I bought a decent gaming PC (Victus 15L) and I'm able to play a lot of my favourite recent games on it in good quality and framerate. So, I started the process anew creating Trespasser's first level, this time in Unreal Engine. The graphics instantly looked so much better when compared to my Unity version. Thanks to the AI revolution in 2022/2023 I was also able to create things I could have only dreamed of before, for example converting textures exported from TresEd into high resolution images (you can see an example of this in the 2 cement blocks right after coming up from the beach). I also recreated the intro using image and video AI and got a really nice image of John Hammond for the newspaper, as it was otherwise only in low resolution available on the internet. I managed to get the same dinosaur models for UE that I had in Unity and it turned out that their ragdolls worked much better here as I found them incredibly obnoxious to set up in Unity.
But unfortunately, there was also a bad side to UE. Unreal Engine doesn't have as many options for paid assets and until today I couldn't find a complex enough Enemy AI driver that supports Root Motion. As a consequence, enemies look unnatural when they walk as the animation of their walking cycle doesn't perfectly match the distance they travel. Also, I found developing in Unreal extremely difficult, I missed the short and easy C# scripts I did in Unity all the time. Or even just small things like the ability to deactivate objects that you had placed in the editor without deleting them was possible in Unity but not in Unreal, which always frustrated me.
In the end, the biggest hurdle I faced though, was yet again performance. In the thickest forests that I created, my framerate goes down to 15, and the forests aren't even that thick. I used one of the best assets for vegetation available and the demo project of that asset pack achieves extremely good framerates on my PC. But when I use the same assets in my Trespasser project, or even when I create a new project and export the demo level of the vegetation pack, my FPS completely tank. I've tried everything I could find in YouTube videos about how to improve performance, especially when it comes to vegetation, but so far nothing has really made a significant change.
Whether it's all of these issues combined or just the fact that I've got other things in life going on, I'm only halfway through finishing one level in UE in the same amount of time as I had finished the entire game in Unity. Sometimes I spent weeks or months not doing anything, which is a problem as in the meantime there are updates to the software and I'm not keeping up. For this reason, I think I'm definitely shelfing this project now."

Trespasser VR (Quest 2) - Demo 2
Requires a Meta (Oculus) Quest 2 VR set.
The second demo released by s13n1 for their VR remake of Trespasser. The demo is hosted at SideQuest where all future updates will be posted.
Trespasser VR (Quest 2) - Public Showcase
Requires a Meta (Oculus) Quest 2 VR set.
An updated demo has been released: Trespasser VR (Quest 2) - Demo 2
"Firstly I want I make it clear this was originally intended to be a simple test just to show how it runs on the Quest 2. It's not an actual demo. It's small, only playable up to the second gate after the shooting range. I decided to add a few more things to make it a bit nicer, but please don't judge it too harshly, there's a lot of work to be done.
Also keep in mind this is a very simplistic version for the Quest 2 and I'm intentionally sticking as close to the source material as I can, with little improvements and fixes where needed. The detail is low, the textures are low res, it's basic, it's supposed to be. A lot of people wanted a more traditional looking version for VR and a lot of people wanted a version they could play on the Quest 2. This is it. I will be building upon this version for the PCVR version, as there are optimisations done for this version that I had planned to do for the PCVR version, but would have been a huge amount of work.
I also want to point out that I'm not a programmer. I can't write code to save myself. I'm primarily an environment artist / designer / whatever. I think the fact I've been able to make this speaks volumes for how accessible Unity is. I've relied on a lot of assets purchased from the Unity asset store, and remade or modified assets from Trespasser. I will at some point list the sources for everything used.
Except for the large billboard trees on the distant hills, there's only three types of trees that have lower LODs, so there's a lot of performance improvements to come. I plan on making LODs and billboards for every species to try and optimize the vegetation as much as possible. The very large trees or trees that are leaning or have wild shapes will probably have more detailed LODs as they usually look bad drawn as a billboard. There's also a lot of trees I haven't made yet. Some are very similar to others, so some of these will be skipped in favor of more unique varieties.
Shadows are.. yeah they're okay. For a while I had them disabled, but they are enabled for this test. They were a bit buggy and flickering so I've tried my best to make them render properly. I messed about with baking shadows but the results weren't great and making simple projector shadows had some rendering issues with other shaders. With shadows turned off, the game actually doesn't look too bad. I'll figure something out.
The Quest 2 seems to have some issues with Zfighting. Objects intersecting the terrain and the road texture are the worst offenders. I'll do my best to reduce it.
There's 2x Antialiasing and for now, anisotropic settings are enabled on everything. It helps keep the rendering clean and crisp.
There are no guns sorry. It would have taken far too long to import the guns and have the models looking acceptable and functioning right with proper sounds and physics etc.
There's just one raptor wandering about on a looped path. I haven't spent any time tweaking them. They're a bit unreliable and often get caught up on things. They don't have proper full body collisions and may not have full sound collisions. I thought about adding some cool scripted events but I might save that for an actual demo.
The dynamic water was a late addition but actually turned out pretty nice. The heightmapped wave generation relies on a subdivided plane, so the larger the plane is, the more subdivisions are needed to create smooth looking water ripples. Obviously the more detailed you go, the bigger the hit on performance. The starting beach is probably the largest body of water in the entire game, almost all others will be a quarter of the size and will therefore be far more detailed.
Swimming is pretty janky. It's just some buoyancy applied to the player. Swimmings not a big part of the game anyway, so don't get too hung up on it. I'll do my best to improve it, but I don't want to waste too much time on it. You can look underwater, there's some simple fog and projected caustics.
There are some fish, seagulls and butterflies to liven things up. They don't land or react to you, they simply move about randomly. I'll probably add more animal varieties later. There's also some dust / pollen type particles floating about in the more vegetation dense areas.
If you look down you'll notice two things. B1 and B2. Yes they made it in. It's just the original mesh for Anne with the arms and shoulders removed and attached to the player with some "jiggle" physics bolted on. I do plan on having a more detailed IK body, with actual female arms and hands. If the chest gets out of alignment, just recenter your view. I'm not sure about adding legs, I'll only go there if it doesn't look too goofy. VR legs can look pretty darn awful. Health will either be a mood stone necklace that changes colour as you receive damage or I might put a tattoo on her arm / wrist. Not sure yet. Whatever looks best.
The backpack is there, it's over your left shoulder. It's just the default Hurricane VR backpack for now, but I do plan on customizing its appearance. What you can store in it for this Quest 2 version is yet to be determined. Don't expect micromanagement of individual bullets and loading mags, this isn't that kind of game.
There's no menus, comfort options or control customisation. It will happen one day, it's not a priority right now.
The file is 182mb, how you sideload it is up to you. Future updates will probably be available on SideQuest
I hope you enjoy it, I've had an absolute blast working on this. I'm excited to see some videos of you playing and building crazy physics shit. I wonder how long it will take someone to figure out a way to physics freak themselves out of the playable area. I'm sure someone will figure out a way!"
Trespasser 2D Demo
"I am sharing herewith the demo version of the JP Trespasser 2D game that I have been working on for the past few weeks. It is still a work in progress and I am wishing to release the complete game for Android and PC platforms shortly. I just wanted the Trescom members to give their valuable feedback and enjoy the game."
"Since I am just an amateur game developer, kindly bear with me if any glitches/ errors that might pop up during the game. It should run fine on PCs with latest Microsoft builds. Kindly let the community members trying the demo to suggest improvements and/or modifications to me @this mail id, so I can refine and give a better version in the final build. Hope you guys enjoy it!"

Trespasser Awakening (Trespasser HD Remake) (Unity Version)
UPDATED MAY 31st 2022 (22m5vE)
"Hi everyone. Here's a little xmas gift for you: The first alpha/demo version of my Trespasser remake. I started working on this 5 months ago. So far, I've got all final 9 levels down in a draft stage. Over the next months, I will continue to improve the enemy AI, the player, the audio, the 3D models as well as adding new mechanics, vegetation, terrain textures, and a weather and day/night cycle. You'll notice the game currently has huge shortcomings in all those areas. Having said that, this is only the second time I ever created a game, and when I started development on this, I had absolutely no clue about how to code. I've poured so much of myself into this game over the last 5 months and I really need a break for a week or two. Anyway, I hope you have fun exploring Trespasser from a new angle; I've added never-before seen species, areas, a few new puzzles and even entire levels. I recommend reading the "Keys" section in the main menu. You can play in third and/or first person. Both have their own issues and switching between them is always problematic. But that's what an alpha version is for ;) Also, I'm still waiting on my dinosaur model supplier to create the Para, so unfortunately you'll not find it in the game yet. At the beginning of this journey, it was my goal to be able to produce a playable build at any time upon demand and it has worked very well so far, meaning I can actually provide updates in a very regular fashion when making changes. Also, at the moment you'll find a few areas that are boring and you just have to run through. I will make it more interesting and engaging and will break things up a bit more. If you feel like you need to advance, just use the first person mode as you'll run faster and have almost no max slope limit. You'll find first person works best in some situations, in other third person works better. Ideas are always welcomed but I'm still a beginner in game design, so I can't promise to create complex situations (just yet)
Installation
Download and unzip the file and just open the Trespasser HD Remake executable."

TPass_QuikShot
A simple game, but I guess somewhat fun. You have 25 shots to take at 20 random targets that pop into view. They're visible for but a short second or so (the smaller ones are worth more points, though harder to hit).
[Easy/Hard mode has been added]
If you get to 1000 points before your 25 shots are done, you'll get a chance to shoot at a flying petradon. That's worth 200 points. That will continue the game with 25 more shots available. Next plateau is 2400, then 3600, 4800, 6000 and so on. . .
There are special targets for October, November, December, and for April and March. For those who know of it, Christmas in July also has the same targets as that of December.
The background is from Enigma's Level 'Christmas Crisis'. The dinosaurs are mostly tresops dinos. Images for special targets were gathered around the web. I have no idea who to give credit to, but I do appreciate their artsy talents. Most of the audio is derived from Trespasser itself -
Well, that's all, folks. Hope y'all get a little enjoyment from it. It's just a little something from the old tresop's team.
