Serious Sam 2 Overdose is a project of mine. It started out because I wanted to change the game. I learned quite a bit and now, I'm creating a mod. Please don't expect it to be like Insamity or Classic mod. Think of this as a... small mod. (FOR NOW ON HALT) (DOESN'T MEAN MOD IS DEAD)
This is a first release to the public. This is beta and it's to check if there are any bugs before the release.
