I'm waiting for this too

My only complaint. It's jarring. May as well have made humans.

I know this is a year later (ive only just found out about the game) but i would have thought they evolved to not have them. Unless they run on all 4s a lot. Like humans evolved to not have tails from monkeys.

Well. If they add it they add it. But a reason they might not is cause. Honestly the tail could cause a few issues. It might be something that is typically amputated for soldiers. Imagine it getting stuck around something before getting out of a tank. Or you're hiding but an enemy sees your tail and then pulls you from the hiding place. Among other reasons they might just wrap it around themselves under the uniform. It also could be a model limitation

Yes

Both

Both.
