On 23 December 2008, weapons were introduced into the game with the release of a "Metal Gear"-themed game pack titled ""Metal Gear Solid" Level Pack". A paintball gun power-up, called the "Paintinator", can be used to activate "Paintinator Switches", can destroy certain enemies, and can be picked up similarly to a jet-pack (which is by simply touching it). The player can also add the Paintinator to custom levels. The game pack includes new "Metal Gear Solid"-themed stickers, music that can be placed in user-created levels, and various character costumes.
