The game uses a side-on 2D view. During a team's turn, one worm moves and attacks before the turn timer expires; players can walk, jump, aim, adjust power, and select weapons from an inventory. Explosions deform the landscape, so every shot can alter later movement and firing positions.

Players progress through campaign missions and training exercises, while multiplayer supports battles between human or computer-controlled teams. Victory usually requires destroying all opposing worms, with survival depending on health, terrain, timing, and effective use of the weapon supply.

Use the terrain as cover, but remember that explosions permanently change it. Short, controlled shots are often safer than maximum-power attacks when nearby allies or hazards are involved.

Save powerful weapons for situations where they can remove several worms or deny an important position. Keep moving when possible, watch the wind before using airborne projectiles, and use utilities such as teleportation or the ninja rope to reach safer angles.
