Roboquest Endless Mode: The Unique Guide to Surviving Infinite Stages

Last Updated on 26 June, 2025

Endless Mode in Roboquest is the ultimate test of your build, reflexes, and adaptability. Unlike the campaign, this mode throws you into an infinite gauntlet of scaling difficulty, stacking modifiers, and brutal boss combinations. If you want to survive past Stage 12 and push into leaderboard territory, you’ll need more than just good aim. This guide breaks down how to unlock Endless Mode, how modifiers work, and how to build a run that can go the distance.

How to Unlock Endless Mode

To unlock Endless Mode, you must either complete the campaign on Guardian 1 difficulty or spend 100 Wrenches at Basecamp to activate the Endless Mode machine. Once unlocked, a portal appears in Basecamp that launches you into a dedicated run. This mode is separate from your campaign progress and cannot be accessed mid-run.

If you’re unsure how to unlock it, this short video by Woomy walks through the process and explains the core mechanics in under three minutes.

Endless Mode Structure

Each Endless Mode run follows a consistent rhythm:

1. Stages 1–5: Early setup phase. Use this time to lock in your core weapon and perk synergy.
2. Stages 6–10: Glitches and Singularities begin stacking. Elite enemies become more frequent.
3. Stage 11+: Duo bosses appear. Perk overflow begins. Enemy behavior becomes more aggressive.

After each stage, you receive either a Singularity (major modifier) or a Glitch (minor penalty). These stack permanently and can drastically alter your strategy. For a breakdown of how these modifiers affect gameplay, the TrueAchievements Endless Mode thread offers community-tested insights and perk combinations.

Best Classes for Endless Mode

While every class can succeed, some scale better in Endless Mode due to passive damage, mobility, or perk synergy:

1. Engineer: Turrets provide passive DPS and scale well with Boosters. Great for crowd control.
2. Commando: Headhunter builds offer high crit burst and early-stage dominance.
3. Recon: High mobility and stealth perks make this class ideal for dodging duo boss mechanics.

Pro Tip: Avoid cooldown-heavy builds unless you have consistent cooldown reduction. Endless Mode punishes downtime and rewards sustained output.

Weapon and Perk Synergy

Endless Mode rewards synergy over raw stats. Focus on one damage type and one weapon archetype. Build around perks that multiply your strengths rather than spread you thin.

Recommended builds:

1. Burn Build: Flamethrower + Firestarter + Burn Booster
2. Crit Build: Sniper Rifle + Headhunter + Weak Spot perks
3. Sustain Build: LMG + Shield Regen + Damage Reduction

Once you hit perk cap, you’ll start receiving Boosters. Prioritize those that match your build. For example, if you’re running a crit build, stack crit damage and reload speed. Don’t waste rerolls on off-type stats.

Understanding Singularities and Glitches

Singularities are major modifiers that can completely change how you play. Examples include:

• All enemies are elites
• No healing between stages
• Enemies explode on death

Glitches are minor penalties that stack over time. Examples include:

• Shields recharge slower
• Enemies move faster
• Random weapon affix reroll

Pro Tip: Don’t underestimate Glitches. Five small penalties can be deadlier than one big one. Track them and adjust your build accordingly.

Duo Boss Strategy

Starting around Stage 11, bosses appear in pairs. These fights are the biggest wall for most players. Here’s how to survive:

• Focus fire one boss to reduce pressure
• Use verticality and dashes to avoid overlapping AoEs
• Save cooldowns for the second boss unless you can burst the first quickly

Pro Tip: If you get a combo like Rocket Golem + Shock Spider, prioritize the ranged AoE threat first. Positioning is everything.

Progression and Optimization Tips

• Use Discovery Mode to test builds before committing to Guardian difficulty
• Unlock gadgets like Jetpack and Hero’s Cape to improve mobility and early perk access
• Farm Wrenches in lower difficulties to unlock permanent upgrades

Final Thoughts

Endless Mode in Roboquest is a brutal but rewarding challenge. It’s not about perfection, it’s about adaptation. With the right class, perk path, and modifier awareness, you can push well beyond Stage 12 and into leaderboard territory. Every run teaches you something new, and every modifier is a puzzle waiting to be solved.
