GlueFO 2.0, from the irRegular creators of Sproing Reloaded, has a simple premise: what if the heroic ship in Asteroids couldn't afford ammunition? What if the global recession were in fact universal, and the only way you could afford to bust space rocks was by sticking drifting pebbles to your hull, and then spraying them at the asteroids like deadly gravel?

This updated version of irRegular Games' Sproing adds weapons and upgrades to an appealing formula: bash apart moving targets with a big blue ball on an elastic band. Sproing Reloaded brings a good mix of simple physics gaming that's hard to master, 30 achievements to keep you coming back for more, and a bit of quirky humor to show you the author's personality.

What irRegular Games has done is to take Conway's Game of Life and apply goals to it. On one level, you might have to maintain a constant number of living cells. On another, you might need to exterminate them all within a certain limit of turns. The reason this works as a game is that Conway's Life is an efficient factory for stories and characters. The winking Traffic Lights. The steadfast Boat. The expanding Bee Hive. And everyone's favorite, the sidewinding Glider... and his nemesis, the Block.
