Plan your next Let Them Come: Onslaught session

Our independent guide breaks down Let Them Come: Onslaught’s core systems, offering observations that help you refine your approach without promising hidden bonuses. By comparing weapon types, progression loops, and map dynamics, you can make informed choices that suit your playstyle and the game’s procedural nature.

01 / THE GUIDE

Weapon‑Upgrade Synergy

Compare a high‑damage flamethrower paired with a shield upgrade against a precision Photon Saber build. Note how each combination handles crowd versus single‑target scenarios.

  • Try pairing a high‑damage weapon with a shield upgrade for survivability.
  • Mix crowd‑clearing and precision weapons to handle varied enemy groups.

02 / THE GUIDE

Build Investment Strategy

Track the rewards earned in three consecutive runs and allocate them to either new skill unlocks or existing upgrade tiers. Observe which allocation yields longer survival.

  • Focus on unlocking upgrades that complement your preferred weapon style.
  • Use each run to test a new combination before committing resources.

03 / THE GUIDE

Map Adaptation Drill

Play three runs in the same world, focusing on how the procedural map changes. Record which landmarks shift and how that affects your route to supply drops.

  • Observe boss attack cues early to adjust your positioning.
  • Reserve high‑damage upgrades for the final boss phase.

04 / THE GUIDE

Boss Pattern Recognition

During boss encounters, after each phase, note attack cues. Compare patterns across different bosses to develop a universal evasion habit.

  • Keep an eye on distant supply drops for extra loot.
  • Adapt your route when random missions appear to maximize rewards.

05 / THE GUIDE

Input Method Comparison

Spend a run using the keyboard only, then another using a DualSense controller. Evaluate aiming precision, reaction speed, and overall comfort for bullet‑hell combat.

  • Experiment with controller vs. mouse for aiming comfort.
  • Enable Steam Cloud to keep your builds safe across installations.
