As months passed by, Adeptus Titanicus more or less stagnated apart from the introduction of smaller war machines called "Knights" (both Imperial and Exodite Eldar ones) and, later, the appearance of the mutated Chaos Titans. Space Marine, however, prospered with the release of a new army list system heavily based in semi-realistic orders of battle with support attachment, multi-tiered command structure and regimental/battalion levels. Imperial Guard, Ork, Eldar, Squat, Chaos, and Tyranid sprues of 6mm figures, artillery and support weapons were released while vehicles came in white metal and were sold in blisters containing, most often, two units apiece (single units appearing only in the case of larger models such as Shadowsword or Baneblade tanks).
