DooT
DooM is an old game notoriously known for its brutality. DooM uses sprites that changes based on the AI's actions. Movement as the doom guy is quite slippery; the movement is as if the character moved on a glacial floor. The sprites are deeply pixelated, which is regularly switching per second. ASCI C is a language used to code DooM itself. It was so fans could easily modify doom themselves if they wished to. It allows the ability to customize angles or height for any walls and floors.
Designs of the game itself showcase a dark atmosphere with demons who appears to be more contrast than the terrain and human enemies. Considering how the game focuses on Hell, there are numerous amounts of creepy sprites that can even be interacted. And to such, this game introduces a bloody genre that was highly controversial in its timeline, yet it is a quite fun shooter honestly.
