First session: Cash Multiplier, Base Size, merges, Trait Machine, and Wave 50 prep before mutation spam.
By Bloxron Editorial Team · Last updated
What you need first
Tower defense by One Billion Six Seven: villains hit your base in waves, you roll fighters, place them, earn Cash, then grow with merges, traits, and mutations. First session: lock Cash Multiplier and Base Size, clear an early wave block with one merged carry, and learn the Trait Machine on the far-left lobby before you spam gacha.
First session steps
Six moves from opening waves to using codes without wasting Cash.
Survive the opening waves with Cash focus
Place your first fighters and let kills fund the lobby. Prefer upgrades that raise Cash per kill over random new unit names while slots are empty.
Buy Cash Multiplier, then Base Size
Cash Multiplier funds everything else. Base Size is next for extra unit slots. Save Luck Multiplier for when you chase rarer rolls and mutations.
Merge matching duplicates
Drag one fighter onto a duplicate with the same name and the same mutation. Merges level the survivor and unlock abilities. A Gold unit will not merge with an unmutated copy.
Find the Trait Machine
Far-left lobby, near the Sell Shop. Select a unit, spend Trait Shards, roll one trait. Each fighter holds one trait and one mutation; bonuses stack.
Plan Waves 20-50 before endgame gacha
Trait your frontline DPS, merge duplicates before rerolling new names, then raise Luck before mutation-event spam. Hourly mutation windows sit on the mutations wiki page.
Use codes after the loop makes sense
Redeem live batches from the codes page once you know where Cash, shards, and spins go. Check that list before treating any update code as active.
Progression route
What to buy and roll as waves climb. Unit, trait, and mutation tables stay on the wiki pages.
Waves 1-20: buy Cash Multiplier and Base Size first. One merged Rare or Epic carry beats spreading rolls across empty slots.
Waves 20-50: put Trait Shards on your frontline DPS. Merge duplicates before rerolling new names, and raise Luck Multiplier before mutation-event spam.
Wave 50+: run mutation windows on a unit that already has a strong trait. Timers and multipliers are on the mutations page.
Endgame: aim for Mythic or Secret carries with a matching mutation and trait. Promo units and live codes sit on the update guides and codes page.
Common beginner mistakes
These habits burn Cash and shards before your economy is online.
- Spreading rolls across empty slots instead of merging one Rare/Epic carry
- Buying Luck Multiplier before Cash Multiplier and Base Size
- Trying to merge the same name with different mutations
- Rerolling traits on weak unmutated fillers instead of your merged DPS
- Chasing Wave 50+ mutation events before your economy upgrades are online
Beginner FAQ
What should I upgrade first?
Cash Multiplier, then Base Size. Luck Multiplier comes after, when you chase rarer rolls and mutations.
How does merging work for beginners?
Same name and same mutation. Different mutations of the same name cannot merge.
Where do I roll traits?
Trait Machine, far-left lobby near the Sell Shop. One trait per fighter; it stacks with that unit's mutation.
Can a unit have both a trait and a mutation?
Yes. Separate slots, they stack. Prefer strong traits on strong mutations.
How do I push Wave 50?
Keep Cash and Base Size healthy, merge a Legendary or Mythic DPS, trait the carry, then use Luck during mutation events. Details are on the units, traits, and mutations pages.
Where do codes fit in?
After you know where Cash and shards go. Verify live vs expired on the codes page before redeeming.
