I recently got into Depot A....didn't find the mutants too troublesome. Blasted them with psi from range and whack them with machete when they close the distance. I am however very annoyed with Sentry Bots. I cannot find an efficient way to kill them. I know EMP grenades will be the go-to but I never seem to have enough of them. What other options are there for bypassing the resists on mechanical enemies?
