Alien Shooter is a top‑down shooter—specifically a twin‑stick shooter subgenre.
Perspective: The camera looks down on the action, like a map view.
Gameplay: You face hordes of enemies from all directions, focusing on fast‑paced shooting.
Controls: Movement and aiming are independent (twin‑stick style), allowing you to run one way while firing another.
While it incorporates light RPG elements (character upgrades) and a horror atmosphere, its core identity is an action‑packed, top‑down arcade shooter.
