Effing Worms Overview
Effing Worms is a quirky action romp where you pilot a ravenous underground worm that wants to gobble everything in sight.
Burrow through farms, city streets, and icy caverns while weaving around mines, barricades, and soldiers who try to chase you down.
Every creature you eat adds length and speed, letting you rocket out of the dirt, snatch helicopters, and slam back underground before rivals catch up.
Chain your dives, bite through bonus crates, and prove you are the hungriest worm in the leaderboard every round.
How to Keep Your Worm Hungry
Rounds are fast, so stay in motion and ride the rhythm between the surface and the tunnels while collecting as much prey as possible.
Smart upgrades matter as much as reflexes—invest in the perks that fit your playstyle before each wave launches.
- Steer with the arrow keys or WASD, and tap the spacebar for a burst that helps you burst through obstacles.
- Chain underground sweeps before surfacing to scoop up birds, cattle, and vehicles for massive combo points.
- Spend the trophies you earn on upgrades like speed, armor, and jaw power so tougher enemies can't stop your run.
