Mutant Year Zero: Road to Eden

Pod Spawners are similar to the Ovomorph creature in the Alien saga, once they detect you or fight start they release random enemies every 2 or 3 combat turns, what u have to do is just kill it before it release an enemy. It's quite simple and u don t have to kill 5 different pods, fastest way is do it on the first pod u encounter, save before start the fight and keep killing and reload save 5 time to get the achievement.
