If you're in deathmatch, aren't you suppose to be able to pick your weapon through the buy menu when you spawn ?
(Sorry i'm not very familiar with this, as this is unrelated to the map itself)

yeah sure but since there are a lot of weapons on the map I was wondering if there was a way to play with respawns and grab the weapons around.
In deathmatch sometimes it bugs out and even if you already have a gun bought it will grab the gun you spawn on
