You have already described exactly what the 890 is NOT. It has a defensive loadout consisting of good armor, shields, and PDW's, not offensive firepower. It is a gigantic touring boat. Go buy an Idris or 3.
How's it going y'all, if you follow the NC Bar Citizen discord you already know this, but we have an event scheduled for the 23rd at 12:15. More info at the top of the post!
They said swimming would be a thing ages ago. It's why out glorious 890's have pools. They also said they were considering boats and other water only vehicles but had not decided on them yet.
