Being an old veteran of tremulous and playing just a little I'd though I'd give my opinion and impression on some things.
The human turrets are way too unreliable.
They take way too long to fire because they have to face the enemy and windup before they can engage.
I suggest the windup be removed and range increased but to compensate, have a limited field of horizontal fire.
This means turrets become more focused on covering entrances over an area, which makes them severely unreliable.
I don't know if I am interpreting this wrong but, does the helmet and battlesuit not reduce headshot damage?
Please correct me if I am wrong but that seems counter intuitive and an unneeded change.
The flamethrower changes are great but as an anti-building weapon, it and the grenade become weak as aliens build on walls.
I suggest the battlesuit makes the wearer fireproof which would help make it far less risky to use.
Painsaw appears to be way too weak right now considering.
The chain-gun is way too inaccurate, in fact it's so inaccurate the screen shake it makes doesn't hamper it at all.
I suggest you dramatically increase it's accuracy, rate of fire, and ammo reserve but reduce it's damage per shot to compensate.
That should mean without a battlesuit unless the alien is facehugging you, you have an actual reason to crouch fire it.
Reduce the damage human buildings deal when they explode to other buildings, right now it's far to punishing to the human team.
Also the medistation's activation animation creates massive FPS drops even on my beast machine, also it obscures vision too much.
The goon barbs regenerate way too fast right now, considering how fast they can destroy buildings and 1-hit humans.
Poison seems unfair, the alien gets to deal extra damage with no effort just because he touched a building.
These are just a few things I felt stood out the most compared to 1.1 and 1.2 on my first couple matches.
