1. Redeploy fast with the bonus
Use the rebirth guide's rule: bank a Nest Egg before the reset so you hatch a fighter the minute you're back. Slot it into the PIT and repeat the feeder-first upgrade order from the beginner guide — your income floor is higher now, so the loop restarts faster.
2. Graduate to Thunder Egg fusion
Nest and Scratch Eggs build breadth; the mid-game is where you start chasing quality. Farm Thunder Eggs from high tower floors and the LETMECOOK code, then fuse their donors onto A-tier bases. Read the fusion level guide so you level the base, not the donor.
3. Set roster and skill goals
Sooner or later you want a reliable A-tier core — Astro Chicken is the dependable pick — while you chase the Mythic Thunder Rooster for the ceiling. While hunting, lock useful special abilities onto that core. Don't wait on Secret draws like 404 Chicken — build the roster, treat the rare birds as upside.
Mid-game alternates between fusion, tower pushes and careful rebirth timing.
4. Push the TOWER on boost windows
Time your climbs with 2x Money or Corn boosts so each floor pays twice. Keep the tower guide's rule in mind: when clear times double, bank the earnings and reinvest in attack or a stronger fuse instead of grinding to a crawl.
5. Time the next rebirth
Your second — and later — resets follow the same signal: when the offered permanent bonus beats the wall you're hitting. See the rebirth count guide for when the cadence slows and pushing tower floors matters more than resetting again.
Mid-game loop summary
Redeploy with the bonus → Thunder Egg fusion → A-tier core + skill locks → boosted tower push → next rebirth. Repeat until the bonuses stop speeding your climb.
6. The mid-game bottleneck is almost always one of three things
When progress slows after your first rebirth, it is usually not a mystery. Check that the PIT is full, check whether the feeder and recycler have moved recently, and check whether your carry has actually been upgraded since the reset. Fixing the bottleneck beats starting another reset — and it beats buying another egg. Run those three checks before you spend a Robux or a reset on a problem you do not actually have.
