So to start it's actually better than I expected, that being said it still needs a fair amount of work.
My top issues are:
Hit registration is bad, like really bad. I've been shot quite a few times and taken no damage. I've also put 10 rounds in a guy's head before he finally goes down and other times 2-4.
Walls don't seem to affect sound so everything sounds like it's happening right on top of you.
Bad hit registration and high health creates a long TTK, combined with the gun having essentially no recoil leads to a lot of spraying full auto. I see no reason to burst, they're either close enough for auto or out in space and require single shot. EDIT: I am against long TTK. From what I understand the actual damage to HP would be an acceptable TTK but with the bad hit registration it makes it waaaay too long.
Massive frame drops every couple of seconds.
Grenades. They throw really screwed up right now, like a half under hand throw. Also, I dislike the screen angle determining over/underhand throwing. That's not in at the moment, but I already know I am not going to like that once it's implemented. Buttons vastly preferred, not screen angle.
I never used the cover mechanics and didn't even bother trying to find them, I just don't think they're worth it and never thought they would be. I don't bother with hand gestures but I did try to help people out in the chat sometimes or give them compliments on clever plays. Unfortunately the chat starts hidden and it's like F11 or whatever to bring it up. It'll definitely need a VoiP moving forward at least in Star Marine. For the PU people can opt to use 3rd party programs or continue to use spectrum. But Star Marine is a random arena game, needs that VoiP.
The game feels much slower than the videos they showed, I am not sure if they slowed it down in patches or not. Right now it's at a speed where I could be happy with it.
My big worry going forward is that the game is so slow I think it will favor camping/defending way too much. Attacking a base/ship is going to be extremely difficult, even with grenades. Without grenades the only viable strategy I can come up with is throwing enough bodies at them to force a reload before going into the room, which given consequences of dying the PU is not an acceptable strategy.
Currently my org and I are signed up for every Star Marine tournament that I've seen. We still plan to compete but the game is not ready for actual competitive gameplay. The hit registration issue alone is a dealbreaker for true competitive play. It's good enough to have some fun stomping the yard, but I'd burst an artery if I took it as a serious competitive game and came up against anyone near my skill level.
Oh and I labeled myself a CSGO player because that's the game I took most seriously. But here's what I've been playing lately to show I've got a good spread of experience in these games:
Titanfall 2
Battlefield 1
H1z1
Rainbow Six Siege
Squad
Insurgency
