Pardon the shameless self promo, but there were a handful of mods for Beta 5 a few months back! I tried to compile the majority of em in the description of this tutorial (all you've gotta do is replace the Assembly-CSharp file, super easy install). The MAJORITY of what people could do was just change colors, so you could flip team colors, or one that was super cool was a "rainbow" mod that made everyone random colors. The most game changing mod that I've got the link to was definitely NueSB's third person mod, but I remember there being a handful of complications with it. I don't really know why these wouldn't still work, but they are kinda old so I guess there's a chance somehow..? Version modding is super specific, so hopefully they work.
