I would love too modify my pred weapons, adding something more vital like perk’s for weapons (fast reload time, the look of the weapons itself, to gain status of “elite” on that weapon and then we get a bonus for that.
New weapons like whips, heavy maul, scimitar. (costumizable, ofcourse)
New armors bases on the film series, comics, etc.
Pred characters as DLC paid.
and many more.
For fireteam-
a “one DUTCH per match” will be good, even tho the lobby will probably take longer, etc,etc.(is just an oppinion)
think about adding more outfits, this will probably boost the plesure to play with fireteam much more as u see your character looking soo badass!
More “lower face covers”
More “full-head covers”
This will boost even the players to play the fire team, too increse that joy. Even the lobby will probably explode at fire team
“start machmaking 1 sec, done, u are in the game”
illfonic, i hope u will do this in the future. And as i said, those are only some ideas.
