Vampire Survivor like games are top-down action games where you move your character and it auto-attacks hordes of enemies. You gather XP and choose from a few options each level up. You end up selecting s handful of offensive and utility capabilities and get ultimate versions of them if you manage to max them out. There are some synergies between the different weapons and items you end up choosing in your build (complexity of synergies varies in the genre.) If you’re familiar with autochess, the leveling/building takes cues from that genre.
