would it be possible?

[GuntherDW]

i have some ideas for enemies etc...

like a super shotgun dude, a bfg shooting cyberdemon (shooting 1 bfg blob)
revenant shooting 2 rockets like in doom3
spider demon with plasma bolts :p
cacodemon firing a lightning strike (?)
etc etc
and for the weapons :)
chaingun rocket launcher (2nd chaingun)
some sort of railgun (maybie u can use the pistol frames for that)
etc...
possible? (without modifying the original ones, so creating new ones, and making new weapons (so u have to press the '4' key twice)) ?

Via Objects.ded you can make as many new badguys as you want,though you have to use existing bad guy attack(s).

New weapons can't be added via ded (they have to be done in the dll). Though you can modify the the existing ones in Values and Objects.ded. Again you have to use one of the existing player weapon attacks.

Though in both the above cases you can use objects.ded to change the properties of any missle to sort of create a new attack.
