Quake 1

really needs to keep the mouse in the flash window if that's possible. I keep not being able to turn right anymore 'cos the cursor has hit the right side of the screen...

other than that, nice 1

Quake is 14 years old? Now I feel ancient.

Granted the game is 14 years old its still pretty sweet that its in a flash version that runs smoothly as far as i can tell. Great for people who've never seen the game but if you've played it before I'd just download the actual game for the best experience.

People keep asking me for flash versions of other games. You don't understand, this is the freeware version of Quake, so I am allowed to port it and upload it to Kongregate. Other games, however, may not have a freeware version or be freeware, and I am not allowed to do anything with those games. That would be illegal.
