About Ben 10 Alien Onslaught

Ben 10 Alien Onslaught is an arcade survival game where aliens attack Bellwood and you must hold them back. Three arenas set the action in Bellwood, the Canyon, and the Null Void, with a different boss connected to each location. Regular enemies arrive in several forms, while successful runs can lead to coins, artifacts, permanent upgrades, and achievements.

The combat stays active because movement and attack direction are handled separately. You can use keyboard movement on desktop or your thumbs on mobile, making the same survival idea work across control styles. The goal is to endure the assault and defeat the boss when it appears.

How to Play Ben 10 Alien Onslaught

On desktop, move with WASD or the Arrow Keys and aim attacks with the mouse.

On mobile, use your thumbs for movement and attack direction.

Fight the incoming aliens while surviving in the selected arena.

Continue long enough for the arena boss to appear, then defeat it.

Use earned coins in the Plumber Shop for permanent upgrades.

Tips & Tricks

1Keep moving while directing attacks so approaching aliens do not surround you.
2Aim toward the most immediate threat instead of leaving attack direction fixed.
3Use the arena layout and your movement carefully before the boss arrives, when enemy pressure is already active.
