Let Them Come: Onslaught Launches on Xbox - Survival Guide

Let Them Come: Onslaught gameplay featuring intense alien combat.

The relentless alien swarm has arrived. Let Them Come: Onslaught, the highly anticipated sci-fi survival shooter, has breached our defenses and is available now on Xbox. This intense, top-down roguelite throws players into a desperate battle against an overwhelming extraterrestrial horde, where every run is a frantic fight for survival. If you hope to last more than a few minutes against the chitinous tide, you’ll need more than just a quick trigger finger—you’ll need a strategy.

Prepare to lock and load as we break down everything you need to know to face the onslaught and live to fight another day.

A New Breed of Alien Shooter

Let Them Come: Onslaught evolves the core concept of its 2D, pixel-art predecessor into a full-fledged, 3D roguelite experience. You are an elite soldier, the last line of defense against an endless wave of grotesque alien creatures. The perspective has shifted to a top-down view, giving you full freedom of movement across sprawling, hazardous arenas. This isn't about holding one position; it's about constant motion, strategic repositioning, and crowd control on a massive scale.

The core gameplay loop is brutally simple yet deeply addictive. You’ll dive into a mission, obliterate as many aliens as you can, and inevitably be overwhelmed. But death is not the end. It’s an opportunity to regroup and re-arm. Experience and resources gathered during your run can be used to unlock permanent upgrades, new weapons, and powerful abilities for your next attempt. Each run pushes you further, allowing you to build a progressively more powerful soldier capable of withstanding the ever-escalating threat.

Mastering the Onslaught: Essential Survival Tips

Surviving the swarm requires a blend of reflexes, tactical thinking, and smart character building. Rushing in blindly will only lead to a quick demise. Keep these fundamental strategies in mind to extend your lifespan and maximize your destructive potential.

  • Movement is Your Best Armor: Standing still is a death sentence. You must constantly be on the move, weaving between enemy projectiles and repositioning to funnel aliens into chokepoints. Master your dodge ability to create breathing room when you get cornered.
  • Know Your Enemy, Prioritize Your Targets: The swarm is not a mindless mob. It’s composed of diverse alien archetypes, each with unique behaviors. Small, fast-moving creatures will try to overwhelm you with numbers, while hulking brutes will soak up damage and larger, ranged enemies will snipe you from afar. Learn to identify the biggest threats in any given wave and eliminate them first.
  • Synergize Your Arsenal: The key to a powerful run lies in creating synergies between your weapons and the perks you acquire. Find a weapon that applies a burn effect? Look for perks that increase damage to burning enemies. Wielding a shotgun that excels at close range? Find upgrades that boost your movement speed and armor to facilitate an aggressive playstyle. Don't just pick perks that sound good on their own; think about how they complement your entire loadout.
  • Think Before You Upgrade: During a run, you'll be presented with numerous choices for temporary upgrades. Be deliberate. If you're struggling with survivability, prioritize health and armor boosts. If your damage output feels low, focus on critical hit chance or raw weapon power. A single well-chosen upgrade can be the difference between failure and reaching a new milestone.

An Arsenal of Annihilation

To combat the alien menace, you'll have access to a formidable and expanding arsenal. The game features a variety of character classes and weapons, each catering to different tactical approaches. You can unlock everything from standard assault rifles and powerful shotguns to more exotic weaponry like explosive launchers and energy cannons.

Your loadout is the foundation of your strategy. Do you prefer to keep your distance, picking off targets with a high-powered marksman rifle? Or do you enjoy wading into the thick of the fight, turning aliens into paste with a close-range scattergun? Experiment with different combinations of weapons, active abilities, and passive perks to discover the ultimate alien-slaying build that perfectly matches your style of play.
