The Scottish resistance looks horrible. Couldnt they think up something better? right off the top of my head here is a good primary unlock.
The Scotsman's Rifle
Only holds 1 shot with 10 in reserve, bombs explode on impact and arc, and fast reload.
Downside is they don't arc as much so firing bombs at angles to hit stuff will be a thing of the past, they don't bounce so no shooting stuff around corners, and there is less ammo.
Since they don't bounce this will become infinitely more useful in combat.
This is 20 times better and it could even be used for pipebomb jumping.
So wtf valve?
