Wideload's Halo-engine zombie game, Stubbs the Zombie, is available for the PC for only five bucks now from Steam. Thanks GameFocus for the heads-up.
Palluxo.com has a (late) review of the Mac version of Stubbs the Zombie. Fair warning: it spoils the entire plot, if you happen to mind that, and doesn't really describe the gameplay.
Alright, let me start of by saying that if you are on insane, you are screwed. Go home. If you are already at home, leave. This level scared me away from the game (and these walkthroughs) for a long time, but now I am back to save those of you stalling here. My apologies, but I wasn’t doing much better. I made it through the level in a couple of hours while writing this guide, so it should be doable. Good luck, and thanks to hawk for inspiring me to go back and face my fears.
