Gameplay.
Each level will have several outposts all clustered together in the center. If an enemy ship touches an outpost, then the outpost is destroyed. The player can activate a long range scanner by using a second button. This allows the player to locate enemies before they get close, thus enabling the player to remove themselves from the game. This ends the life of the player's gaming platform.
