Phalanx

The player's ship can switch to different speeds at any time, allowing the player to move fast to avoid enemies and obstacles entirely, or slow down to weave between enemy bullets. An unusual addition for a shooter is the ability for the player's ship to take multiple hits before losing a life. A variety of weapons can be picked up from items that certain enemies leave behind, and up to three can be stored at a time. The player can switch between these weapons freely, and sacrifice a weapon to produce a "smart bomb" effect, freeing up the slot to grab another weapon.
