Acheron is a 32-bit visual first-person shooter developed by TheNek where you play in an arena full of demons on a kind of red planet / hell. The game features four types of enemies, various weapons and a boss.
The game is very similar to FPSs like Quake, Doom and several other titles from the 90s. Here you face waves of demons with different attacks that attack and move with great speed. There are 9 waves of enemies, with an indecipherable boss that looks like a type of walking energy and does a lot of damage.
The game is short and can be finished in less than 10 minutes, however, we didn't finish it due to the extremely high difficulty of the boss who moves faster than you.
