Let Them Come: Onslaught

Let Them Come: Onslaught is a roguelike alien-survival game with bullet-heaven combat and a retro sci-fi setting. You fight through waves of aliens, build weapon combinations and try to survive long enough to face towering bosses. Runs take place across four distinct worlds, with procedurally changing maps and dynamic events.

Weapons and progression

You can unlock weapons including flamethrowers and Photon Sabers, each with its own playstyle. Upgrades let you combine weapons and special effects into powerful builds, with options for clearing crowds, targeting enemies or using shields. Between battles, you spend rewards to unlock and improve skills, refine your strategy and push further into enemy territory.

Survive the waves

As the alien assault intensifies, you must use your reflexes and tactics to stay alive. Survive long enough and you face towering bosses. Special mini-bosses can appear unexpectedly, while distant supply drops offer helpful loot. Random Missions add optional objectives that you can complete for rewards.

Characters and worlds

You can play as one of two characters: The Soldier or The Psychic. The game includes four distinct environments, with changing maps and events during runs.
