First of all, I like the new fx, cryo stream and decals look much better.
Ice dart projectile looks neat. The impact effect is a nice touch, however, it currently looks more like an exploding snowball. Maybe those white particles could be more 'sharp'? Or at least a bit smaller and faster moving.
Lights on the gun indicating ammo level is a very nice touch.
The muzzle smoke in primary fire is perfect, however, in secondary mode I'd say it's too severe, obstructs vision a lot. Perhaps it could be even removed altogether, as updated cryo stream graphics will make it sufficiently foggy
The thing that kinda doesn't make sense is that the gun generates flash while firing. It is not that much of an issue when using primary mode, but the light it continuously casts around upon releasing cryo stream looks just strange. Imo light at firing should be removed in both modes.
Shatter effect is nice (perhaps chunks could be a bit bigger? right now they are too small to even represent a mass of a shattered crawler), but zeds killed by ice shards doesn't shatter, just go ragdoll while maintaining icy texture, which still looks silly, especially when playing as sharpie, but also when for example, you just kill a crawler with 3 icicles. Can shattering effect be applied if zeds die by any damage source while frozen? Because I doubt people will change weapons after freezing a small zed to finish it.
Balance-wise, didn't do a lot of testing, but so far 5x damage for weapons other than explosives/shotgun pellets kinda makes sense, gives a sharp
some kind of countermeasures vs frozen zeds and is absolutely lethal when coupled with commandos, however, I'd still prefer a solution without removing headzones.
Reduced splash radius of the cryo makes you use a bit more of ammo to keep multiple zeds frozen, but is far from resolving corked corridors issue.
More of bug report: stalkers frozen during attack are guaranteed to become idle if you move away from their melee distance. It sometimes happens with other zeds, but stalkers seem most vulnerable to this bug. As with pretty much anything that messes with the zed speeds, the gun can be used to trigger slowbugs in scrakes and gorefasts, but I understand that's an issue within the KF code, not the cryo.
