Zombie Monster Survivors

Zombie Monster Survivors casts you as a brave survivor in a world holding both zombies and monsters, which matters because the two do not behave the same way and a tactic that handles one will not always handle the other. The game's own advice is the useful summary of it: keep moving and attack the large waves rather than trying to hold a position. Resources are limited and using them wisely is framed as part of survival rather than a side system, and coins and energy collected during a run feed into the skills you choose. That choice is where runs differentiate themselves, since the same extreme environment plays differently depending on what you picked.
