Base 2 Base is a Half-Life 2 Multiplayer Modification which puts 2 teams against each other (Red & Blue) and they have to fight to reach a teleport that is above the enemies base. When a player from that team goes through the teleport they are teleported to a safehouse where they can watch the battlefield on a monitor. First team to have all of their players through the teleport into the safehouse wins, and if a player is in the safehouse and wants to return to the battlefield they can do so by suiciding.
