Half Cash on Ascent turns the map into a demanding resource-management challenge by halving starting cash, income from Bloon pops, end-of-round rewards, and other income sources. Ascent’s exceptionally long paths give your towers valuable extra time to damage Bloons, helping compensate for the limited budget and making efficient tower placement especially important. The key is to avoid unnecessary purchases, prioritize towers that can handle multiple threats, and save enough money for major checkpoints such as the Round 40 MOAB and Round 63 ceramic rush. With careful spending and a defense built around Ascent’s long tracks, you can overcome the reduced income and complete all 80 rounds.
