Melee locking is still possible, but it's a lot more trickier to do.
Not really a good counter we've been trying to get zerk nerfed for years as well.
Someone doesn't understand the Slowpoke meme. :[
So, it costs over 6000 credits(lvl 6 sharpshooter) to refill M99 AMR, a gun that is bolt action, that has only 25 bullets and that prevents you from equipping anything else besides default pistol.
It's hard to imagine getting it any more wrong, so it's a bug?
it's the biggest (or one of the biggest) mistakes tw ever done in kf and i still hope for balance
however i was playing with 9mm + m99 on hard i never filed ammo just had few bullets for fps and we were doing fine but on suicidal or hoe it's suicide
