For posting and discovering the start of the steps and more.


Also I ran with cheats because I wanted to explore the EE and find out what was next. And I got my highest down's of all time lol.

On dog rounds go to an area where dogs do not spawn behind you and go prone as I missed the hit boxes a lot [skill issue]

On AAT canister step's. Make sure to round them up and use the weakest gun I chose the machine pistol P...something Sorry I forgot,
