It is a brutal test of your D&D skills, a gauntlet of sudden-death traps and bizarre monsters strewn across countless dungeon levels. The DM will show no mercy. The dice will grant no quarter. It's just you Against the Slavelords.
In the early days of D&D, TSR held huge tournaments at gaming conventions to see who could defeat the most monsters and survive a gauntlet of deadly traps. One of the adventure series written specifically for such a tournament, Against the Slave Lords, got the deluxe reprint treatment recently. All four of the original adventures, known as the A-Series since they're labeled A1 through A4, are together in a deluxe binding with all of the original art at a retail price of $50 (my review copy is bound backwards and upside down, but this seems to be a single printing error and not a systemic problem).
