Many FPS games like Nexuiz usually have a setting called Weapon stay for a game session. When enabled, picking up a weapon from where its placed on the map gives you that weapon with the default ammo but the weapon does not disappear from the pickup location and acts as an infinite supply, though you are not allowed to pick it up again if you already have it. If disabled weapons act the way they do now and when picked up they disappear then respawn again after some time.
This would be really helpful, not only because it's a classic feature that's missed out but also because in maps with many players, even if weapons respawn soon people still have to wonder around with the shotgun because they cannot find a better weapon until one appears back. So please, can you add the Weapon stay flag in the next release? At least as a mutator though that's normally a server setting when you make the server.
Note: To already highlight a possible glitch; When implementing this, make sure that a player cannot drop the weapon they already have, pick the weapon from the pickup place when Weapon stay is on then pickup the one they thrown again, thus being able to gain double ammo. In UT this is blocked by not allowing the weapon you throw to be picked up if you re-picked it from the pickup place when weapons stay.
