Crimsonland (PC, 2003)
There's nothing like unrepentant killing to get the blood flowing. (We mean in video games, of course.) Indie developer 10tons, whose work is probably better known in the iPhone/iPad games market, got a taste of success early on in their existence when they put out Crimsonland in 2003. The game challenges players to blast their way through increasingly difficult levels of monsters as they attempt to surround and overwhelm you. After more than half a decade of developer support and expansion to mobile devices, the game is supposedly in the process of getting a much-needed sequel. Hell, if Wii Fit can nab a sequel, CrimsonlandÂ can too, right?
