only works on the quakespasm spiked source port
[QUAKESPASM SPIKED]: Fte.triptohell.info
apparently conversion of all md3 .png textures to RLE compression .tga 32 bit fixes transparency issues on FTEQW


Description:
This mod was created from my love for Doom 3, it adds enemies and weapons from Doom 3 to quake, no model lerping is best for the mod.

weapon cycle = impulse 30
weapon cycle reverse = impulse 31

Differences from Doom 3:
Besides being on idtech2 and not having sprinting, running speed is decreased to 280 ups, all enemies have been rebalanced to have *more* health and do *more* damage. Certain enemies act almost differently to how they were in doom 3, imp and knight balls are now grenade likes. *All* enemies has been made to be more aggressive, this combined with more health and damage causes the game to be rather difficult*. So much more evil design choices lies within.
*All* weapons has stats changed including how much ammo they can hold.

Enemies:
z-securities, trite, cherub, imp, boney, hell knight, cacodemon, archvile, mancubus, bruiser, vulgar, demon, revenant, commando (tentacle), maggot, wraith, lost soul ( i forgot if there are more...)
Weapons:
fist, pistol, shotgun, machinegun, chaingun, grenades, rocket launcher, plasma gun, big fucking gun 9000, chainsaw

Works somewhat on FTEQW. Totally not working on vkQuake. Regardless, I'm happy someone finally did it. I love DOOM 3!
0/10 too scary

Easy
Great mod, needs a little bit of tweaks, if possible.

- reload weapon when mag is empty
- switch weapons when no more ammo.
- chaingun chews trough ammo atm (might need dedicated levels with more ammo)

I wish there would be .fgd or .def file for it, to make levels in Trenchbroom.
Also , would be nice to work on Ironwail

-reload weapon when mag is empty
it existed in prior versions but removed to make the game more challenging, of course i will add it as a Cvar in the future it is planned (similar to doom 3's auto reload setting)
-switch weapons when no more ammo
thats a bug i forgot to fix it xp
-chaingun chews thru ammo
probbaly up to preference

.fgd i could make one
working on Ironwail would be impossible to pull off unfortunately
yay!! doom 3 !!!
ermmmmm ironwail port WHEN.... this is getting ANNOYING....
