I know this is probably too early to know or the devs say, but how will basic unlock go? i did see some level up mentioned in the trailer but what will that progression actually affect? how will weapons be unlocked? Will it follow the basic COD and BF route of character XP or weapon type XP? will it be the old "rent-a-gun" model from older F2P shooters?
Same applies to the factions and gadgets for you loudout? Can you pick any character and have all gadgets and skills for that faction or only cleaner character will have the turret gadget but share all of his secondary perks with other cleaners and the ultimate being the same?
At this time we don't know how levelling up and what will be available and how the methods of unlock will work. I personally hope the method of unlock is relatively straight forward and isn't a grind sesh of like 100 hours to get one gun maxed out. I think COD Does it best, it'll take a few hours or maybe 5 or so to fully max out a gun if you're playing well. It means you feel that constant move and progression.
What I really don't want to see if a pay to win model where you just drop some coins or cash or whatever the currency is and you skip a rather steep grind.
It really impacts the moral of your team.
