Developers, doublesix have sent word that All Zombies Must Die! will finally be invading Steam on March 12. It's a top down arcade blaster that has you taking on the zombie hordes with up to three friends. The minute-to-minute corpse obliteration is deepened by a layer of RPG sweetness that will let you level up your zombie slayer and craft new weapons.
As well as a few nice extra bits like leaderboards and achievements, the PC version will improve on the console edition with a new "treacle" mechanic to give survivors completely surrounded by undead a chance to wade through the smelly ranks and make a break for freedom. The difficulty curve has also been adjusted to temper the harshness of its final stages.
