The hero of Let Them Come has the right idea for when you’re trapped in a shadow facility ovverun by hordes of ravenous alien horrors. No hiding, no sneaking about, just get a big gun and hold them all off for as long as you and go down fighting. That tile is a statement of intent, challenging you to face pixel-art waves of enemies and bosses in this new shooter out now on iOS.

Let Them Come is almost as simple as that title implies; from behind your stationary heavy weapon, you attempt to survive increasingly tough pixel-art foes, complementing your main gun with special ammo, secondary items like grenades, and perks and upgrades to modify your loadout.

Lacking the movement of dual stick shooter or shmup may seem limiting, but Let Them Come injects variety and skill through both the diversity of monsters you face, and the precision needed to prioritize enemies. From swarming insectoids to shambling infested corpses to shielded behemoths, different aliens are best defeated with certain explosives or ammo types. Survive and you‘ll unlock both new gear to eauipe and mixtapes to listen to. Fail and be devoured.

If you can want to put extraterrestria slaughtering skills to the test, you can purchase Let Them Come for $1.99 on the App Store.
