Sequel design 101: Make your game bigger. Given one of the only complaints fans had with the original PixelJunk Shooter was its length, the explosion of content in the sequel makes sense. Over a year in the making, Shooter 2 has bigger bosses, bigger levels and a bigger feature set. But, bigger doesn't always equal better; while Shooter 2 will keep fans busy, it's one of the few "disappointments" from the studio's otherwise impeccable portfolio.

The most significant addition to the Shooter formula is the new competitive multiplayer feature. I was skeptical at first, doubtful that PvP would be able to retain the game's unique charm. I was proven wrong with my first online battle. The subtle changes to the core mechanics make for an interesting game of cat-and-mouse. Just like in the main game, you must rescue survivors. But, in versus mode, there's someone else hellbent on rescuing more of them than you.

Each of the maps offer different strategic options, taking advantage of the unique liquidity of the game's levels. Risk maneuvering through an active volcano to avoid enemy fire, for example. Or, try having a shootout in the water, to avoid heating up. Flashier players may even try to steal survivors from an enemy base.
