Inside the frantic world of Let Them Come: Onslaught

If you’re in the mood for some fast-paced chaos, Let Them Come: Onslaught brings exactly that. At its core, the game is all about taking on never-ending swarms of aliens while you try to survive just one more wave. Each run feels self-contained and punchy, letting you jump straight into the action without any fuss. You pick a loadout, dive into a wave, and immediately get surrounded by monsters that keep piling in from every angle. It has that “ok, one more try” vibe that makes it super easy to sink an evening into without realizing.

A fresh look at wave survival games

What really makes Let Them Come: Onslaught stand out is how over-the-top its arsenal feels. We’re talking flamethrowers, photon blades, orbital nukes, psychic blasts—basically everything short of summoning a small sun. The game leans into the fun factor rather than realism, so the moment you trigger a ridiculous combo or wipe out a whole screen of enemies in one swoop, it’s genuinely satisfying. The retro-sci-fi aesthetic adds to the charm, and the run-based structure means you’re constantly experimenting with new builds. You never quite know what kind of crazy loadout you’ll end up creating, and that unpredictability is half the fun.

The game also shines with its replayability. Each run plays out differently thanks to random events, mini-bosses, new areas, and all sorts of modifiers that keep things spicy. Even when you lose (and you will), you still walk away with upgrades that make the next attempt a bit stronger. There’s no big storyline weighing things down—it’s pure action and progression, perfect for short bursts of chaotic fun. And while it’s simple on the surface, there’s plenty of depth in the way weapons and perks interact, giving you that satisfying “build crafting” loop.

If you enjoy chaotic wave survival games, you’ll feel right at home with this one. It’s especially easy to recommend if you’re into fast-moving, arcade-style shooters that don’t take themselves too seriously. And if you like games such as Vampire Survivors, Brotato, Yet Another Zombie Survivors, or even the original Let Them Come, then Let Them Come: Onslaught is definitely worth checking out.
