Project Clean Earth: How to Unlock and Build the New Body

To unlock the new robot body in Project Clean Earth, spend your saved gems in the chassis customization menu accessed from the main hangar screen. Equipping this frame shifts Bernard from a fragile hit-and-run unit into a durable frontline fighter, boosting survivability against dense mutant hordes at the cost of slight handling agility.

Chassis Stat Profile and Combat Role

Unlike lightweight baseline frames that rely on dodging and outrunning chaser units, this body focuses on absorbing contact and retaliating against surrounding swarms.

Attribute	Base Frame Profile	New Chassis Adjustment	Gameplay Impact
Durability (HP)	Moderate baseline	Significantly increased	Absorbs explosive mob bursts without instant death
Movement Speed	High agility	Minor handling reduction	Requires tighter turning and deliberate pathing
Passive Trait	Standard utility	Defensive retaliation	Deals passive feedback damage to attacking swarms
Collision Buffer	Low resistance	Enhanced knockback immunity	Prevents Bernard from getting trapped by enemy hitboxes

Because the reduced agility makes outrunning fast chasers harder, you must position intentionally. Orbit the outer edges of enemy clusters or hold choke points, letting the frame's defensive stats and retaliation passive soak chip damage while your weapons clear a path.

Recommended Weapons and Card Synergies

The increased base durability allows Bernard to fight comfortably in close-to-medium proximity. Build your deck around sustained area-of-effect (AoE) output to capitalize on grouped enemies:

Primary Weapons: Prioritize orbital drones, radial lightning strikes, and expanding wave emitters. These weapons deal continuous damage immediately around the frame. Avoid single-target sniper tools unless an encounter consists entirely of isolated bosses.
Support Chips: Equip cooldown reduction cards to cycle defensive barriers and shockwaves faster, compensating for lower mobility.
Sustain Cards: Add life-steal or recovery-on-kill chips to continuously replenish health while fighting inside dense packs.

Navigating the Updated Challenge Mode

The game mode introduced alongside the new chassis restricts arena space and accelerates enemy spawn rates, testing your sustained damage and crowd control.

Circle the perimeter early: Move along the zone boundary during the opening seconds to scout hazards and establish a clear circular rotation route.
Eliminate aura elites: Direct heavy fire at champion mutants carrying aura buffs before swarms overwhelm your defensive threshold.
Anchor central choke points: Once the initial rush subsides, move toward the center so converging mobs funnel straight through your radial weapons.
Hold cooldown bursts for collisions: Save manual screen-clearing skills for sudden elite clusters, relying on passive retaliation for standard minion collisions.

Upgrade Investment Order

Do not spend all your nanites and chips exclusively on chassis levels. If offensive card upgrades fall behind, swarms will eventually outpace your damage output regardless of your health pool.

Level the chassis to its first major passive threshold to establish baseline durability. Next, invest resources into your top two primary AoE damage weapons. Once standard enemy waves clear reliably within seconds, resume leveling the body's secondary defensive nodes for higher-tier stages.
