How do you do that.
You can do that for any character. But all of them have very limited powers (Galactus more than the others, because he doesn't pass through doors), and for most of them, there are mods you can use.
But, to play as any NPC character, decompile 'npcstat.engb' from 'data' folder, copy all the character info, for example
stats {
aiforceranged = true ;
body = 1 ;
characteranims = 18_galactus ;
charactername = Galactus ;
(... stuff)
strength = 1 ;
[b]team = enemy[/b] ;
textureicon = 38 ;
(... more stuff)
talent {
level = 70 ;
name = monst_dmg_high ;
}
}
open herostat, paste the character lines, CHANGE line team = enemy to
team = hero, ADD line
playable = true ; and ADD line
menulocation = XX ; you can also change more stuff if you like
