3 0 1The sentry bot is a craftable item. The schematic can be bought from Coffer in Wellspring. All you need to do is use it in a crowd. It is extremely powerful and won't have any issues taking down the needed kills.Showing only comment. This is easily done in Mutant Bash Tv area, shrouded bunker or in dead city during one of the unlock locks sequences, where several mutants spawn to attack you. You can activate the sentry just before. There is another spot where a sentry comes in hand, spoilers: *** Spoiler - click to reveal ***When you enter the defib upgrade room and claim the defib itself, there will go around 5 seconds or more before a toxic mutant bursts through a wall with 3 other normal mutants. You can deploy the sentry long before they breach the wall. Posted by Sivarg on 19 Mar 21 at 04:20
