What makes a good action game? Usually tight controls, a satisfying rhythm once you learn the patterns and short, intense rounds — and Guerrillas.io has each of them in some measure.

Tips and tricks
- If there is a dash, jump or dodge move, treat it as a resource: use it to escape, not to attack, until you know the level.
- Keep moving. Standing still is the most common way to lose an action round, because the game is designed to punish hesitation.
- Watch the edges of the screen, not just your character. New threats almost always enter from the sides or the top, and spotting them early gives you a full second of extra time.
- Learn the enemy or obstacle patterns before you try to go fast — most action games repeat a handful of behaviours, and once you recognise them the game slows down in your head.
