Had a 160 Ping on the Server and nonresponsive Weapons thanks to that. But not much you can do about my bad Ping I guess.
Ony played for a bit, Respawning is very slow on the Server, the Spawnpoints are clearly visible, when they should be hidden, All the Guns fire too slow, if not Way too slow, thats too long of a Cooldown in my Opinion. Projectile for the Harpoon gun also seems rather Slow, I couldn't try it, as noone was online and my Ping trash, but I don't think it'd be able to hit someone with that at least semi-reliably.
I'll play more when theres a public Testtime with actual People online. Hopefully my Connection will also be better then.
Edit:
ParticleColors and Muzzleflash for the Nailgun(?) Seems off, reminded me more of a Biocannon. Also seemed to fly through Player sometimes, but maybe thats due to the Lag.
