REBELUTION is a multiplayer mod set in the Half-Life 2 universe, where the rebellion has been experimenting with cybernetic technology with the intention of being able to fight the Combine army back. Defend your position as a rebel or destroy the new lethal technology as an Combine Soldier. The choice is yours.
While nigh-impossible to play due to the amount of bugs right now, as soon as this is out of beta, I am certain this game will be excellent. it needs more people playing it in order for it to be tested, but it should turn out to be a very nice game, kind of like if team fortress (2?) and half life 2 had a baby.
