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)
Even though people said "Forget about Multiplayer" I didn't, just made a map for DM called "Sirius Fight" Screenshot made in Editor.
