Yea, not really interested in this especially since the characters/masks really have no effects and are just cosmetic...and even then when you play anything besides free for all your character is coated is just smeared in red or blue and you can rarely tell the difference between person to person.
20 Trails: Great, too bad they only grant adam which doesn't help a ton because you can easily amass adam through hacking/vials/research etc...
The trials have no real reward in themselves.
Rank 50: Pretty much the only reason they are raising the rank is so that you have to earn the new weapon attachments, I guess this is meant to just fool people into thinking they are earning their DLC content instead of it just being handed to them. Seriously think about it, if you just forked over the cash and the weapons you'd be like..huh I paid for some cheap skins and weapon attachments...
Also wasn't the point of rank 40 that the first protagonist comes crashing in and you're off to go bust his head open?
So in the end the DLC really isn't much of anything its custom skins and weapon attachments, the trials and rank is pretty much pointless.
