Hot Fuss: Robokill 2
Hurrah! Robokill's back. The original game had both Walker and I write a little around, and now there's a sequel. In short - it's a Smash TV/Robotron versus Diablo cross, with you upgrading your little mechanical fellow while working your way through a maze of rooms. While there levels and monsters are all new - and the monsters seem much smarter - almost everything we said in the original pieces holds true. As in, the pits are annoying (though there's less of them) but it's really good fun, the rumble of your multiple-guns builds up and it's well worth playing, especially if you haven't touched it before. Video follows.
And, I stress, this is a fan-made trailer rather than one which Rock Solid Arcade have done. As such, the \m/!!!!! metal isn't exactly characteristic of the game.
It's a premium flash game, which means while the first episode is free, to play the other two you'll need to throw down ten dollars.
