Let Them Come: Onslaught brings retro bullet heaven to Xbox this November

Table of Content

Let Them Come: Onslaught arrives as a retro-styled, sci‑fi bullet heaven where survival hinges on buildcraft and crowd control. Each run asks players to mix and upgrade an arsenal while navigating hazards that can hurt – or help – depending on how they’re used. The official announcement outlines the core systems, from invincibility frames and dash chains to Level‑3 weapon breakpoints. Below are the key facts and mechanics highlighted by the developers to help players prepare.

Release details

Release date: November 11, 2025. Platform: Xbox Series X|S. The game leans into fast runs, build experimentation and escalating alien waves typical of the bullet heaven subgenre.

Survival fundamentals – what the official guide stresses

• Keep DPS scaling: Offense should rise steadily during a run, supported by Armory upgrades between attempts to maintain pressure on the swarm.
• Layer your defenses: The level‑up Shield blocks one hit and recharges on cooldown; pairing it with Health Regen and Armor Plating can significantly extend survival.
• Use i‑frames: Temporary invulnerability triggers after taking a hit, when a Super Shield expires, or after the Soldier’s dash. Knowing the timing lets you slip through dense packs and reposition.
• Chain dashes: Multiple charges can be linked to remain untouchable through large waves – chaining preserves invincibility across the sequence.
• Health economy: Health packs reliably come from common crates and can drop from mini‑bosses. A level‑up option adds +150 Max HP and heals for the same amount – a late‑run lifesaver.
• Damage triage: Larger enemies hit harder. If you must trade damage, take a hit from a smaller foe (e.g., Spiderling) then use the resulting i‑frames to escape tougher threats.
• Credit income: Credits primarily come from common crates and mission rewards. The Armory’s Extermination Contract upgrade can grant bonus credits for mini‑boss kills. Defeating a level’s main boss triggers a bonus enemy wave that drops credits. Completing a level applies a credit multiplier, and Hard Mode adds an extra multiplier.
• Missions vs. supply drops: Mission rewards are shown upfront and distance to the target is indicated – prioritize missions when the reward fits your build and time allows. Supply drops are unknown until opened and can be a better call if the mission window is too tight.

Weapons, breakpoints and synergy

The arsenal covers pushback, sustained damage and area control – the key is balancing roles and investing to Level‑3 where many tools spike in power.

• Level‑3 breakpoints: Shotgun gains Double Shot; Electric Grenades fire in pairs; Flamethrower applies burn. Builds that stall often spread upgrades too thin below Level‑3.
• Crowd control choices: Shotgun vs Repulse – Repulse offers stronger all‑around pushback; Shotgun deals higher damage and inflicts a movement slow. Running both improves survival but may reduce boss damage output.
• Auto‑aim sustain: Autogun and Blaster both auto‑target nearby enemies on low cooldowns. Blaster requires standing still to ramp fire rate; underwhelming early, it becomes a high, nonstop DPS option at higher levels, especially for bosses.
• Randomized AoE: Electric Grenades vs Rocket Barrage – both fire randomly and deal large area damage. Grenades land closer to the player; Rocket Barrage targets farther out. Taking both boosts output but relies on RNG to hit priority targets.
• Role balance: Mix pushback, targeted damage and area denial. Some weapons excel up close, others at range – complement strengths rather than duplicating roles.

Environmental hazards and positioning

Levels include threats beyond enemies. The official guide notes that hazards can be avoided or turned to your advantage with smart pathing and timed dashes. Positioning, crowd funnels and i‑frame timing collectively dictate whether a build survives late waves.

Final takeaway – how to approach your first runs

Build toward Level‑3 power spikes, preserve i‑frames with chained dashes, and treat credits and health as economies to stabilize mid‑to‑late waves. With clear roles for each weapon and measured defensive layers, players can navigate the alien swarms more reliably once Let Them Come: Onslaught launches on November 11, 2025.
