Retro Serious Sam
What would it look like if Serious Sam was released in 1994? Well, I don't know but Batandy definitely does. He has released another nifty trailer for his project Serious Sam - The Retro Encounter. It is a fan made, freeware DooM mod that aims to recreate Serious Sam's gameplay and provide a balanced multiplayer and an unique Serious Sam style campaign. You can find more videos and information in the official thread over at ZDoom.org.
