Field guide
Survive.
Grow stronger.
KRAIVORN is a browser-based 2D survival game. You start alone, fight off waves of creatures, collect experience, choose upgrades, and prepare to face bosses.
How a run works
Every system serves one goal: survive longer and set a new anonymous record.
Use WASD or the arrow keys. The map follows the hero and expands after every wave.
Creatures drop blue orbs. Pick them up to fill the next-level bar.
After leveling up, three random cards appear. The chosen effect lasts until the run ends.
A powerful boss arrives before a new creature type appears. Defeating it opens the field shop.
Upgrade cards
The higher the rarity, the stronger the effect. Luck increases your chance of receiving rare, epic, or legendary cards.
