Synopsis
Deus Vult is a highly modified version of 1SQUARES.WAD by Costa Lappas. Most battles take place in makeshift "arenas" with cliffs, teleporters or hallways separating each area. This is also true of 1SQUARES.WAD, with doors being the "separators" between rooms. The first battles feature monsters at the player's eye level, with increasing height differences as the player progresses, as well as the areas and monster counts growing ever larger with each wave.
