Yep, believe it or not, here comes Bitsofglass Physics 2.0!!! Why changes so soon, you ask? Well, you see, I got a request asking for underwater shooting weapons. Your wish has now been granted!!! All weapons (including the flamethrower and fusion pistol) fire SAFELY underwater. All except for the spht' bolt rocket launcher that is. It is the fastest underwater propulsion method known to man. Just hold the key in which direction you want to go and fire away. Trust me, you'll be there in no time. The only downside to v2.0 is that the fusion pistol, even underwater, will still kill you if shot at close range!!! Have fun!!!!!!!!! :)
The fusion pistol still may lock up your computer, so be careful. Otherwise the description pretty much sums it up.
