Undead Empire: Hellfire is an indie multi-directional shooter that has players mowing down endless hordes of horrific baddies, all in an attempt to stay alive as long as possible. As zombies and other nightmarish monsters swarm the screen, you’ll repeatedly kill them all to complete a level, where you can then purchase new weapons and upgrades in preparation for the next wave.
This is certainly nothing new, and comparing this indie gem to classics like Robotron and Geometry Wars is more than fair. What switches up the typical formula is the ability to select different characters, each bringing to the table unique assets for your killing pleasure. You can then team-up with up to three friends, and the four of you can brave the swarm of undead as a group – which may be the only way to survive the onslaught.
