The three currencies
Everything you earn feeds three pools: Credits (common, from missions), Alloy (uncommon, from events and salvage) and Cells (rare, from bosses and milestones). The entire upgrade economy is a currency-conversion problem — the players who win are the ones who never convert wastefully.
The merge rule
Three identical modules merge into one of the next tier — Common to Rare to Epic to Legendary to Mythic. The trap: merging modules you still use. Always keep one equipped copy before merging the surplus.
What to level first
- Weapon damage — the only stat that scales through the entire campaign.
- Magnet radius — it compounds every pickup for the rest of the game.
- Shield recharge — matters from stage 6 onward; early levels are wasted.
The Mythic wall
Mythic modules require a catalyst dropped only by endgame bosses or event leaderboards. Budget your alloy: a full Mythic merge costs roughly 41 Commons in raw material. Chasing two Mythics at once halves your speed — pick one.
The alloy trap
Alloy is tempting to spend on mid-tier upgrades. Do not — it is the only bottleneck currency for Mythic work. The Unlock Concierge computes optimal spend order if you want a second opinion.
