The Laser Blaster (参式レーザーガン/拡散ミサイル San-shiki rēzāgan/Kakusan misairu?, lit. "Participation-type laser gun"/"diffusion missile") is an optional Level Up Item available for E-102 Gamma in Sonic Adventure and Sonic Adventure DX: Director's Cut, and later for Miles "Tails" Prower and Dr. Eggman in Sonic Adventure 2 and Sonic Adventure 2: Battle.
The Laser Blaster is a weapon enhancer that which differs in appearance between each user. For Gamma, it is a small tri-barrel cannon that can be equipped on the front of Gamma's homing missile launcher. For Tails, the Laser Blaster is medium-sized laser cannon that is placed entirely over the missile launcher located on the rear of Tails' Cyclone. For Eggman, it is similar to Tails' version, but much larger and imposing and is placed entirely over the missile launcher on the left side of the Egg Walker.
When equipped, the Laser Blaster allows the user's Lock-On Missiles to release violent explosions upon contact, thus damaging enemies that are near the target as well.
In Sonic Adventure the Laser Blaster is found within the Egg Carrier. It is located in the water reservoir that is found in the room on the opposite side of the armory in the Egg Carrier's main room. However it cannot be obtained before the water pool is drained, which happens after the Egg Carrier crashes into the ocean in E-102 Gamma's story. Once this has happened, the player should head back to the Egg Carrier and into the room where the Laser Blaster is located. The water will now be gone and the Laser Blaster can be obtained.
Sonic Adventure 2
Tails' version of the Laser Blaster is located in Prison Lane, in a room behind a set of bars next to the Goal Ring. To obtain this Level Up Item, Tails must possess the Bazooka, which is needed to break the iron crates that blocks the path to the room. In order to open the barred room, Tails has to destroy the Gun Beetle which is hiding in the upper left-hand corner. This will open the cage and the Laser Blaster will be available for the player to collect.
Dr. Eggman's version of the Laser Blaster is located in Iron Gate. To obtain this Level-Up Item, the Large Cannon must have been previously collected. Right after passing the second Star Post, there will be a room with four ring jars. In front of that room there are two water tanks. The player needs to destroy them, and doing this will reveal four iron containers. The Laser Blaster can be found behind them after they are destroyed.
In other media
The Laser Blaster makes an appearance in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. In this media, it is one of the weapons of the Freedom Fighters' Sky Patrol and resembles Dr. Eggman's version from Sonic Adventure 2 and Sonic Adventure 2: Battle. It was first deployed to destroy the War Walrus when it was sent to destroy the Sky Patrol.
- The Laser Blaster is the only Level Up Item to return from a previous game, yet not be used by the same character that used it in its debut game.
