Gear up for some raw arithmetic violence!
In Zero Sum, every bullet is an equation and every enemy is a number. No health bars. No hit points. Just pure mathematical combat in a hand-drawn twin-stick shooter that looks like your math notebook came to life and got angry.
The Demo is available during Steam Next Fest and includes a substantial chunk of the full game:
2 out of 6 maps
10 out of 22+ weapon modes
3 out of 9+ bosses
35 out of 80+ upgrades
Whether you’re blasting numbers with division, nuking them with modulo, or pulling off stylish combos for bonus RP, the demo gives you a proper taste of the full chaotic experience.
→ Play the Zero Sum Demo during Steam Next Fest (June 15–22)!
