## What is K1?

The lab is running wild and the experiments have escaped! Together with the little robot K1-NK, you place Tesla coils, capacitors and cryo towers before the invaders reach the reactor.

Short rounds of 1 to 4 minutes, perfect for a quick break, but with real tactics: every figure has its strengths, cover blocks line of sight, and combos like Shock Frost make all the difference.

• 2 worlds with 12 levels and a boss each • 3 difficulty tiers per level, collect stars and blueprints • Upgrades and power-ups in the lab, switch them any time • Endless mode with worldwide and friends leaderboards • 16 Game Center achievements • Completely free: no ads, no purchases • One-handed portrait play, works offline

And better not annoy K1-NK too often…
