Gundam Battle Assault 2 encompasses plot lines, characters, and Gundam mobile suits from many of the series' most famous shows, allowing players to square off against their favorite characters in heated 2D battle. Gameplay modes offered include Versus modes that allow players to compete against either human- or computer-controlled opponents, two different Time Attack modes, and a Survival mode that sees players going up against an endless wave of attackers. The so-called Street mode allows players to follow three different story lines -- with one of eight different pilots -- taken from the G Gundam, Gundam Wing, and Mobile Suit Gundam shows. Each of the 'missions' in Street mode is a fight bookended by simple dialogue and taunts between the two combatants.
