Space War is a modern take on Space Invaders in a 3D environment, where the classic gameplay mechanics remain intact but are adapted to an additional dimension for a more dynamic experience. The player controls a spaceship positioned at a fixed base in the center of the screen, similar to the original Space Invaders. Alien enemies descend in an organized fashion from the top of the screen, but in this case, they have freedom of movement in all directions within the 3D space, creating new attack dynamics.

The goal remains the same: eliminate all waves of enemies before they reach your ship, but with a 3D twist. Enemies can move left, right, up, down, and even approach or retreat from the player’s ship, requiring constant adjustments in aiming and strategy. The player can also move along the 3D axis, allowing them to dodge enemy fire and find better positions to attack. Throughout the game, power-ups for weapons and defenses can be collected, and the objective is to achieve the highest possible score by eliminating enemies and surviving all waves.
