does that mean you'll release the medpack/ammobox too?
Yup. The medpack will be released as separate add-on, the ammo box will come with the weapons.
Another thing, I am going to improve my handheld explosives by giving them a small explosion radius, but a big fragmentation radius. It won't shoot actual projectiles in all directions, it'll just simulate it (If not behind cover theres x chance that y to z damage will be dealt). Explosives are just horribly overpowered when they can kill players behind huge walls.
