PLAY RED FACTION OMG FTHGHTHGHTHTHFFHTHGHTFHTHGHTHFH
This game is incredibly awesome, people. If you don't know, it's like 3 games in one; you have the single-player campaign, Wrecking Crew, which is like a "fuck some shit up" lightning round, and excellent multiplayer modes featuring badass backpacks with jets and sonic earthquakes and battering ram energy fields.
Also, experience points, levels, and unlocks. You love that shit, don't you?
