* BUMPSPECIAL flag: actors with this flag will run their special if collided on by a player
* WEAPON.NOAUTOAIM flag, though it is restricted to attacks that spawn a missile (it will not affect autoaim settings for a hitscan or railgun, and that's deliberate)
* A_FireSTGrenade codepointer, extended to be parameterizable
* The grenade (as the default actor for A_FireSTGrenade)
* Protective armors à la RedArmor: they work with a DamageFactor; for example to recreate the RedArmor from Skulltag, copy its code from skulltag.pk3 but remove the "native" keyword and add DamageFactor "Fire" 0.1 to its properties.
