Secret Encounters are hidden battles that award you with Weapon Points. This Doom Eternal Secret Encounter Location Guide will tell you where to find each of the Secret Encounters we’ve discovered so far but beware, these can be challenging and difficult for most players.
Secret Encounters do not actually count as a secret. However, they are special encounters that are otherwise hidden and unavailable until discovered. If you are able to defeat the enemies within the required amount of time, you get an additional Weapon Point to improve the modifications on your weapons.
