Robotic Legs (Unreal)

introduces tech legs cat

This level is almost impossible. The tech legs have 200k hp and 5000 dmg + level 4 wave. BUT that is not the main problem. Supreme Base is the problem due to being able to OHKO your cats except those with "Supreme-Base Immunity" which makes cats with it take 0 damage from supreme base. Make sure you have Tech Tank (immune to supreme base and blocks waves like mk3)

Use long-ranged attackers with Supreme-base immunity (like Stretchy Cat or Colossus, The Hero) to destroy the tech legs and supreme base. (Be wary that tech legs can get healed by Supreme Base!)
