Heavy Mach was just recently updated, and included in the update is a survival mode, and a bullet shell effect. The bullet shell effect is basically just the bullet shells flying out behind you when you fire your turret, and it's kind of cool. The new survival mode is a nice addition, but a bit slow. Sometimes there will be 15 seconds without any machines coming at you, and when that wait is over, about 10 come on, and lag up the game. Although this mode is fun to have, it is WAY too easy, and I hope in a future update they'll tweak it to make it more challenging. http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=304416840&mt=8 There's the link, if you want to check out the game and haven't already. No new screenshots have been posted, although I'm sure some will soon.
