It is found here:somebody wrote:The object of Geometry Wars is to survive as long as possible and score as many points as possible by destroying a constant, ever-increasing swarm of enemies. The player controls a claw-shaped "ship" that can move in any direction using the left thumbstick, and can fire in any direction independently using the right thumbstick. The player can also detonate a bomb that destroys all enemies currently visible on the screen. The game takes place on a rectangular playfield. As the game progresses, the player earns extra lives and additional bombs, and his/her primary weapon changes at regular intervals. Also, enemies spawn in progressively larger quantities and at greater frequency as the game progresses. If an enemy touches the player's ship, it explodes and a life is lost. The game is over when the player loses all of his/her lives.
The Evolved version of the game takes place on a playfield that is slightly larger than the display area of the TV screen, and the camera follows the player's movements. A background grid pattern adds to the graphical effects by warping in reaction to player shots and the behavior of certain enemies. This version of the game also introduces a score multiplier that increases to higher levels as the player survives and destroys enemies.
Enemies in the original and Retro versions of Geometry Wars include:
Light blue diamonds, which move slowly toward the player.
Magenta boxes, which move more quickly. When hit, this enemy splits into three smaller boxes that swirl around toward the player.
Green boxes, which also move quickly. They attempt to avoid the player's shots.
Red circles, which move very slowly. When hit, they become powerful gravity wells that attempt to suck in other enemies and the player, while also repelling the player's shots. Each time an enemy is sucked in, the circles grow in diameter. If allowed to grow large enough, they explode and send a swarm of smaller circles toward the player.
Enemies in the Evolved version include the above enemies, plus:
Purple pinwheels, which move slowly and in seemingly random directions, serving more as obstacles to the player rather than as direct threats.
Light blue triangles, which appear in huge swarms and attempt to overwhelm the player with their sheer quantity.
Red claws, which take aim and charge toward the player, emitting a shot-repelling force field in front of them.
White snakes, which appear either in the corners of the screen or in a circle around the player and "wiggle" their way toward the player. Can only be destroyed by shooting the head.
