The fast-paced roguelite shooter presents different challenges and rewards across procedurally-generated maps, ensuring no two runs are the same. Your Soldier, Psychic, and Mech player characters can equip weapons inspired by sci-fi movies, from flamethrowers to photon sabers and orbital nukes, while enduring escalating alien swarms and colossal bosses.
The SoundCloud and YouTube Music playlists feature every track created for the game, highlighting themes of gritty retro sci-fi, atmospheric tension, and high-octane action. Cover art is by Laurène Bonnet.
Music is by Cartridge 1987, a featured artist on the Rollerdrome soundtrack. The musician is known for arranging the Retro Découverte Vol. 1 vinyl, originally featured on the YouTube channel devoted to exploring old-school console gaming's hidden gems.
Let Them Come: Onslaught is available for PS4 and PlayStation 5, Xbox One and Series X|S consoles, published by Digital Bandidos. The Windows edition is hosted on Steam, alongside a playable demo, both verified for use with the Steam Deck.
Tuatara Games director Klemen Lozar commented via Steam that Nintendo Switch port is deep in development—"the next big thing on our roadmap!"
