Yup... still working on that project I should of finished ages ago...
The engine itself is coded, I'm now writing a level editor in c++
using OpenGL and SDL.

Hopefully it will be all done and finished this month...
no promises though.

The basic engine is based off 2d tile maps which are presented as pseudo-3d maps with height differences... sort of somewhere between Ultima underworld and ROTT. There is a simple particle engine for handling blood, gunshots, explosions and gibs, very simple enemy routines... (In short, the enemies intelligence won't blow your mind but will be enough to cause a bit of a challenge).
Maps have a max size of 50x50 tiles.

Well, hopefully I'll post a demo soon.
