The Battle for the Reichstag, April 28th-May 1st 1945
Including a revised map with larger hexes, and all errata included, this version of Heat of Battle's Historical ASL module details 10 historical scenarios and full campaign rules for the Soviet assault on Berlin.
Also included is a small sheet of 56 counters, including Gestapo Leaders, dug in tanks (treated as pillboxes - including King Tigers!) and numerous others.
Oh, and Hitler.
The game requires the ASL rules, Beyond Valor, Yanks, Kampfgruppe Peiper II, and also references Red Barricades.
(all are required for expansion play)
