As of right now, I cannot recommend playing as scout. She's got great speed, and great abilities... but her invisibility camo ability straight up does not work.
I don't know what it is, but it cancels itself once you get out of stage 1 half the time. Some people have told me it has something to do with picking up contracts in the store between stages. But it still happens outside of those circumstances... so I don't know.
Scout is fun, when she works... but her increase in speed and crit shots from her laser sight make up for the incredibly jank camo ability. Also her starting shotgun weapon is pretty damn strong.
