There are many different Secret Encounter ‘mini mission’ sections to find and locate during your adventures in Doom Eternal.
Unlike the ‘mini missions’ you get in order to obtain the Empyrean Keys, these encounters are mainly based on killing specific demons all within a certain time limit.
It can be tricky to kill these demons within the time limit too as there can be quite a few of them and some areas are rather small which means its easy to get slaughtered instead.
Anyway this page will cover how to defeat and complete the Secret Encounters that are found during Mission 7 – Mars Core. Mars Core has a total of 2 different Secret Encounters to find and defeat, one with Revenants and Gargoyles and the other one features Archviles and Whiplash
The first one you will probably encounter will be the one featuring the Revenants and Gargoyles, this one is actually quite easy as you can just fire a single shot from your trusty BFG and in doing so this will completely eliminate all of the demons in the room. If some of them still remain then just take them out with whatever weapon you have invested more time and effort into.
As for the other one, you can do the same thing and use your BFG again to make quick work of it all. However, if you do not have any ammo for the gun considering the ammunition for it is quite rare you can also just use your Rocket Launcher and whatever else you deem useful.
