• Teleports the player to a random room on the map. Has a chance to teleport the player to the secret room.
• Has a very small chance to teleport the player to the next chamber. If the player is in the Keep of the Lead Lord or the Gungeon Proper , it also has a small chance to teleport the player to the Oubliette or Abbey of the True Gun , respectively.
• Has a very small chance to teleport the player to a room with a large eyeball.

• Production Model - If the player also has [Prototype Railgun] , its shots can ricochet up to five times.
• Second Accident - If the player also has [Shotbow] , its firing pattern is changed to a line of nine arrows perpendicular to the direction the player is facing.
• Telefrag - If the player also has [Chest Teleporter] , if the Teleporter Prototype teleports the player into a room with enemies, all enemies in the room will be killed instantly. If it teleports the player to a special room, Teleporter Prototype's cooldown is decreased. Also grants an extra active item slot.
• Teleporting to the eyeball room will unlock [Yellow Chamber] .
• Teleporting out of a boss room after being hit (then killing the boss without being hit) will not grant the player the [Master Round] for that boss.
• Using the [Bloodied Scarf] you can blink past the invisible wall that blocks you from walking past the eye. Behind the eye there is no wall, just black space that you can enter. If you walk all the way back and blink into part of the main chamber, the game will soft lock.
• When teleporting to a Shop, there's a chance to get behind the counter, right near or behind the merchant. In this case, the player can still go back in bounds again without trouble.
• Has no effect in Boss Rush or the Resourceful Rat's Lair .
• If used next to a minecart, the cart will remain highlighted as though within interactable range.
• After the [Drill] is used, Teleporter Prototype has a small chance of teleporting the player into the room created by the [Drill] . It is recommended to not use Teleporter Prototype after using [Drill] , as teleporting to a room created by [Drill] will prevent the player from using the map teleporters, softlocking the game.
• If playing co-op, and a player uses Teleporter Prototype while the other player is in slow motion weapon select, the player whom did NOT use the Teleporter Prototype will be frozen from all in game action other than pausing the game. If used in the Keep of the Lead Lord there is a chance to teleport to the room with the Oubliette trapdoor, without the need to douse the fireplace.
• Bug: If the player uses Teleporter Prototype during the Dragun's first phase, the Dragun remains idle when they reenter the arena, unable to attack. The Second Phase will resume as normal afterwards.
