I was curious and I caved and bought it. After playing three rounds, I caved again and gifted it to the guy I mostly play D3 and Overwatch with. It's damn good fun and tense as fuck at times.
We duo queued and I showed him the ropes. Made it to the mid 30's then ran it again. He died early after we mis-communicated our landing zone target. I was close to the center of the contracting play zone and spent a super tense 10 minutes holed up in a building under grenade assault. But I was well equipped and they fled, or were ambushed by someone else. When I was forced to move I got my first kill before dying to the zone field.
I love that games are relatively short and that it is relatively deadly. I love that there is relatively little hand-holding, no kill cam, no directional damage warnings, etc. If you are caught in the open under fire, you are in trouble. It adds tension to just the traversal aspect of the game.
Hopefully they keep focused and polish what's there. It's a bit janky in places but seems pretty mechanically complete. Dev seems keen on the 'realism' angle, so there is additional bullet physics on the way apparently - penetration, deflection, drag, etc.
