Ben 10 Alien Onslaught

Morph between alien forms, dodge swarms, and blast everything that moves before the onslaught traps you in a corner.

Ben 10 Alien Onslaught drops you into a top-down arena where waves of enemies pour in from every side. You're Ben Tennyson, and the Omnitrix is your best friend. Movement is WASD or arrow keys, and you aim with the mouse—classic twin-stick setup. On mobile, both thumbs handle move and shoot. It's simple to pick up, but the swarm pressure ramps up fast. The cool part is swapping aliens. Each one changes your attack pattern: one might fire rapid plasma shots, another swings a heavy melee arc, a third drops area-of-effect bombs. I kept switching to the flying alien just to reposition when a wave cornered me near the crates. You'll need to decide whether to hold ground or kite enemies around the map. It's not a breeze. Early waves fool you into thinking you're invincible, then the screen fills with projectiles and you're scrambling. The arena has cover but it breaks down, so you can't camp forever. I died more times than I'd like to admit before learning to save the heavy-hitting alien for clustered groups. If you enjoy frantic action with a decent learning curve, this one bites back in the best way.

Desktop: Move with WASD or Arrow Keys and use mouse for attack direction. Mobile: Use your thumbs to move and attack direction. Follow more instructions inside the game.

• Keep moving in a wide circle to avoid getting pinned by spawns. • Swap aliens right before a big wave to reset your attack pattern. • Use explosive aliens on clumped enemies, not single targets. • Destroy crates early—they drop health and power-ups. • On mobile, keep both thumbs near the center for quicker turns.
