Hello, Disposable Worker #42, and thank you for joining humanity's new energy harvesting operation on Evil Angry Planet. As you've probably guessed, your new work assignment is a bit on the dangerous side, so your paycheck will be adjusted to include regular amounts of hazard pay based on how many aliens you have to fend off while you oversee our latest mining operation. Please do your best to survive for at least a week, as the office pool is providing a payout to all of us who bet that you'd last at least that long.
Irate Games is certainly an ambitious little studio: its freshman iPhone game, Evil Angry Planet, looks like it may be one of the deepest tower defense games to come out in the App Store yet.
