Hell O City sets in a post-apocalyptic world, or a "dying world", as the developer describes it. So you might have guessed the plot: nuclear war, mutant humans...
I really appreciate the design of the monsters in this game. It's creepy as hell and made me wow. I wonder where did the developer get the inspiration from.
In terms of gameplay, the game didn't disappoint me, but it's not very exciting (challenging) to play either. Hell O City is a turn-based roguelike dungeon crawler. Would be great to add more cards and difficulties to the game, IMO.
