Quartet (mquartet.map)
Author:  Martin Brentnall
Type:    BloodBath (2-3, Trap Arena)
Details: A corridor crossroads separating four distinct areas.  A unique
         feature of this map is that all doors can be locked and unlocked.
         One area features one-way walls, where unsuspecting opponents may
         be crushed or blown up via switches.
Secrets: In the Lock Control Room, activate the far wall to reveal a hidden
         area containing items.
Other:   This was probably my first map to contain significant use of traps
         as an element of play.  The locking doors kind of spoil the map a
         little in my opinion.
