Don't you just hate how those Spider Mines jump at you from out of nowhere in (Team) DeathMatch?
Well, hate no more - here comes
No Deployables.
Description
No Deployables removes all deployable pickups, except for the Shaped Charge, which may be required to destroy barricades in some levels.
The Nightshade and Stealthbender remain unaffected and can still deploy Spidermine Traps, EMP Mines, etc.
