The Evil Within Wiki

My Best Friend is an achievement in The Evil Within.


This achievement is unlocked by completely upgrading one weapon through the use of Green Gel.


  • As Green gel is usually limited, it would be wise not to rush this, as it might compromise upgrades for Sebastian's other vital attributes such as Health and Stamina.
  • Since upgrades are carried over to New Game+, players can continue working on their weapons on their second playthrough.
  • Some Easter Eggs award large amounts of gel, which could be exploited to help expedite the process.
  • Rushing this achievement along with its subsequent ones would actually be easiest if the player is attempting to unlock It Is What It Is as well. Due to the lack of allowed upgrades, a player attempting this will conveniently have a lot of accumulated unspent gel on hand, which can be dumped all at once into a cheap weapon (e.g. a Handgun) to quickly max it out. It would be best to do this on a separate save file, however, to avoid messing up the other achievement's progress.
  • Ammo stock upgrades do not count towards this achievement.
