well after playing some skulltag invasion, i got a mod idea for any ID tech 4 game that it would be possible to make one...anyway here is the idea
You will play as different marines from different places in this world (depending where)
Classes should be like any game.
Light Gunner (dunno name for these Guneers xD)
weapons can be DOOM kind of weapons but somwthing better too (BFG should not be in game, too powerful :p)
Assault Rifle (more like ET:QW kind or just improved M4)
Plasma Rifle (maybe the DOOM 1 plasma rifle look)
Heavy Machine Gun (no chaingun this time)
Small machine guns (SMG)
And some Turrets
there should be 2-3 different kind of Assault rifles and the SMG
the map should be ET:QW big maps or maybe a little smaller, aslong it gets some outdoor enviroment in different locations (Jungle, Desert, Forest, City and so on)
Veichle can be something good in this, well should probably be normal military jeeps, a tank and maybe a normal car XD
Now to the demons.
if youve playd the mod Fragging Free, you can control demons and use their skills, wich was a very unique thing in a mod.
The demons should be all the original demons from the DOOM games BUT only some of them can be controlled, if a player wants to play as a demon.
Baron of Hell (should be added and playable)
Commando (the chaingunner thingy)
this is just these i can think of that would be good to play as
the game would be the type of Invasion with number of wave, if the player amount would be around 10-20 players the numbers of monster should be 300-1000 of them each wave
and at last wave, there should be a boss wich will be a very strong hell knight or the classic bosses Cyber Demon (first boss in doom 1) and Spider Mastermind (last boss in doom 1)
so.....what do everyone think of this? :) and nooo i would never mod, its hard :p this was just an idea :)
