Game Overview
Alien swarms pour across neon-soaked battlefields in a frantic survival shooter built around escalating chaos. Let Them Come: Onslaught pairs the one-more-run pull of a roguelite with the screen-filling firepower of modern bullet-heaven games, all wrapped in a grimy 1980s sci-fi aesthetic. Its tone is knowingly excessive: flamethrowers, energy blades, orbital strikes, and mutant hordes turn every run into a loud last stand. Cartridge 87’s synth-heavy soundtrack gives the carnage a fitting arcade-nightmare pulse.
Runs revolve around surviving increasingly vicious waves while moving through procedurally assembled maps, collecting drops, handling sudden events, and reacting to miniboss interruptions. You choose between the straightforward Soldier and the more unusual Psychic, then shape each attempt through weapons, upgrades, defensive tools, and effects that can radically change how you approach a crowd. Some builds favor constant area damage and aggressive close-range clearing, while others reward careful positioning, precision attacks, shields, or devastating cooldown abilities. Bosses serve as real checks on movement and build quality, and optional missions offer extra rewards for players willing to take on riskier objectives. Persistent unlocks between attempts expand the available arsenal and skills, so failed runs still feed into future experiments.
What separates Onslaught from a basic horde shooter is its emphasis on weapon personality and improvisation. A Photon Saber demands a different rhythm than a flamethrower or a screen-clearing nuclear strike, while random map elements prevent a single loadout from solving every encounter. Four worlds provide changing backdrops for the invasion, though the main appeal remains chasing stronger synergies and surviving a little longer than before. Fans of Vampire Survivors-style build crafting who want more active movement, a harder-edged retro presentation, and a stronger action-movie flavor should find plenty to like. Newcomers can enjoy its immediate pick-up-and-play shooting, while genre veterans get the most from mastering its combinations and pushing into its toughest waves.
