One Way Heroics may cost next to nothing to buy, but it is one of my favourite low-budget games. The premise is simple, but the unlockables, seed-generated worlds, and the different endings keep things fresh for a decent amount of playtime. Clearing the game with each class (and each alternate outfit of each class) gradually opens things up for you. You might need a guide (or some lucky NPC encounters) to figure out how to get the different endings though, haha. This is the original, standard edition, with an cheap expansion DLC available, that like the game itself, is incredibly cheap during any sales. Apparently there is a remade version of this game, but it wasn't recieved as well due to certain design choices and differences in balance.

These may just be cheap bundle leftovers, but please only enter it if you plan on playing it. I get that we all have backlogs, so its cool if you don't play it straight away, but please don't enter if you are only looking to boost your game count, y'know?

With that said, good luck! :)
