Add a brighter colored uniforms for the Husks to help distinguish a bit in the dark
While the Stalker may have telltale spikes, being able to see a red shirt a bit in the dark might help you know a husk is with you.
It could add to both sides, you can see a stalker vs a husk, and a stalker can see a husk easily.
As of right now it seems Stalkers are at a small disadvantage, but thats just me.
