Hi everyone, Old but gold: Serious Sam a lot of action, hordes of enemies, coop with maybe 42 players (SS Classic Revolution, on creating a lobby max is 42 players), multiplayer works over steam server, god bless no more gamespy :D It's a good price for the fun you get. Sadly the offer ends in 45min so grab it quick. https://store.steampowered.com/bundle/2656/Serious_Sam_HD_Gold_Collection/
