One of the best action games on the PS2 and still one of the best mech action games. It's fairly short, but it allows for quick replays on higher difficulties. The campaigns momentum never lets up and every section of the game has some unique gimmick to it. City defense, destroying airships with a super weapon, navigating through minefields, fighting alongside an entire army against an enemy force in the 100s. By the end of the game you've unlocked so many powers that you feel like you're on a completely different level compared to the start of the game. The final power letting you instantly teleport behind enemies from long range and one shot them is incredible.
