Brace yourself for a relentless roguelike alien assault in Let Them Come: Onslaught, where bullet heaven gameplay collides with the gritty spirit of retro sci-fi classics.
Create the perfect build from an arsenal of over-the-top weapons and explosive upgrades, shredding alien hordes in a display of retro-fueled chaos. If you’re seeking a survivors-like experience with an 80s sci-fi action vibe, set to the pulsing beat of a soundtrack by Cartridge 87, this game sets itself apart from the pack.
Unleash your inner action hero with weapons straight out of your favorite sci-fi flick, from flamethrowers to Photon Sabers and more. You can even nuke the site from orbit - it’s the only way to be sure. Each weapon brings a distinct playstyle, and upgrades let you stack up devastating combos. Whether you prefer crowd-clearing firepower, targeted precision, or life-saving shields, you can tailor your loadout for maximum carnage (and maximum style).
No two runs are ever the same. Between battles, build craft and invest your hard-earned rewards to unlock and enhance new skills, refine your strategy, and push deeper into enemy territory. Experimentation is key—try different weapon synergies, combine special effects, and perfect your approach until your unstoppable build leaves nothing but alien rubble in its wake.
As the alien onslaught intensifies, your reflexes and tactics are put to the test. Survive long enough, and you’ll face towering bosses that demand every ounce of skill you’ve honed. It’s the ultimate showdown, straight from the adrenaline-drenched heyday of retro sci-fi action. Gear up, lock ‘n load, and get ready to Let Them Come, because the Onslaught is about to begin!
Fight your way through four distinct environments. The map always changes, and many dynamic elements will challenge the player during runs. Special mini bosses that spawn when you don't expect them. Supply drops with helpful loot will spawn in the distance. And Random Missions will force the player to complete optional objectives if they want to reap the reward.
