The Physics in this game are amazing
As you may know, the game runs on the Havok Engine, making it capable of things that GTA could NEVER do. Things I've found are as follows:
-Anything that's not an object on the MAP can move
-You may not be able to drive the El Train, but it can still derail
-There's a boat near a drug trafficking activity that moves. If you can weigh it down, it may sink
-The trailers to trucks have NO invisible barriers
-(i'm sure you've figured this out) bullets may still kill motherbleepers as Johnny Gat put it, but so do flying car parts
That's all I got for now. But any other's are welcomed. I'm still lookin.
Rest in Peace
