Wiki Abilities

All 12 Passive Abilities in TUSG.io

Permanent upgrades bought with ability points — always on, no cooldowns.

Where skills are the buttons you press, abilities are the character sheet underneath: 12 permanent passives that shape how fast you move, how hard you hit and how much everything you eat is worth. Most players start with Mass Increase or XP Boost — compounding passives pay best when bought early.
