I've been waiting for an Infectonator sequel for a while, now, and I was more than pleased with the results. Your goal is still the same: eliminate the world with a horrifying zombie virus. The scope of the game has increased dramatically, however, with TONS more levels, a lot of upgrades, much-improved graphics, and a better sense of humour. There's almost no point in playing the original Infectonator anymore, as number two is better in virtually every way.
WorldBox isn't so much a game as it is a simple simulator. You have a world, you can build more of a world. Or take it away. Or other stuff. This is basically a very limited version of a Sim game with few consequences if you lose. It's not that great, but it appears to be a base for something a hell of a lot better, and I look forward to whatever it might create in the future.
Endless War 6
You are tank. You blow shit up. That about does it for Endless War 6, like the previous games. There is OTHER stuff to consider, of course, but it boils down to mashing your opponents. I haven't played the previous games in the series, but I like this one, if for no other reason, for the fact that you get to drive alongside a bunch of other troops. You're part of a coordinated whole, and that's pretty cool.
