This mod was a fun one back when I made it in 2011. I was only 16 and still new to programming and was into messing around with game code. I managed to pull this together using some neat modelling tools.
It was basically just a hacked boat, with physics to go up when you are in it! Real good fun, shame I never managed to release it. I think the only reason I didn’t was because it didn’t really do anything and I really wanted to hack it into being controllable.
The video doesn’t really do it any justice, but just to show it actually flys.
