Marathons' very first Red Rarity or Contraband weapon debuts with the release of Cryo Archive. It is without a shadow of doubt that the Biotoxic Disinjector is the best gun in the game, and nothing even comes close to it. The weapon has 2 modes of firing, a laser beam mode and a grenade launcher mode, either of which turns enemy Runner Shells into a steaming pile of goo.
What makes the Biotoxic Disinjector the best gun
The weapon's stats initially seem lacking; with only 17.6 Firepower, you may be questioning its use. But it also comes with a staggering 1000 charges per magazine. The craziest part is that each grenade launcher shot consumes only 22 charges and is fully automatic, essentially making it a futuristic war crime dispenser. The large magazine, coupled with a decent explosive radius, makes cover genuinely irrelevant; it makes each trip to the surface of Tau Ceti IV a blast for you and a loading screen simulator for your enemies.
How to get the Biotoxic Disinjector
Getting the Biotoxic Disinjector is no easy feat, but the gun is well worth the effort. To obtain this weapon, your team must first defeat The Compiler, who is located in Vault 7. But getting to Vault 7 is no easy task, as your team would need to complete Vaults 1 through 6 and also loot each vault's AI Subroutine.
Reaching Vault 7 is a long and complicated process that requires a well-coordinated team to complete. Luckily, we have a guide here to help get your team all the way to The Compiler. Once you beat The Compiler, you can gain access to the loot room, assuming you have Security Clearance Level 5. The weapon is guaranteed to spawn in one of the chests, but as far as the quantity, only 1 spawns at a time.
