Description
About This Game
In a world where cultists desperately need to be shot...
What, Were You Expecting A story?
Oh, Alright.
You are *checks notes* Gary, an unassuming nobody with no backstory, personality or, for the moment, voice, who got kidnapped by an evil cult aiming to summon their god into this reality. You are the final sacrifice. And you're having none of it. You break out of your cell, and kill literally everybody so the cult cannot summon the great evil they worship.
3D enemies? 3D weapons? No. The enemies, the weapons, most of the props are all 2D sprites. What 3D models there are are crude and low-poly. Texture resolutions are abominable. I even wrote a special shader that lowers the apparent colour depth.
Commitment to the 90s aesthetic is near absolute: The sole exception is that the weapon viewsprites are normal mapped, which is anachronistic but looks so good.
Shoot all the bad guys! Or hit them! Or kerplode them!
Defeat your foes with these bog-standard FPS weapons:
Unity? UE? Build?
No.
That would be easy.
Hecatomb is coded entirely in GameMaker. I had to do everything 3D myself. Among the things I had to figure out are:

Reinventing the Wheel
Unity? UE? Build?
No.
That would be easy.
Hecatomb is coded entirely in GameMaker. I had to do everything 3D myself. Among the things I had to figure out are:
- Drawing walls and ceilings without tanking performance
- How sprite-based enemies move
- Shaders to restrict the colour palette
- A normal mapping shader for the weapon viewsprites
- How to calculate the position of bullet holes in a wall (it uses the tangent!)
- How to bake lighting into the map
- How mouselook works (Note: vertical mouse look is implemented, but disabled.)
- And many more that cropped up over the months but I can't think of right now.
