Semper Fi is a
turn-based strategy game in which the player commands a
Marine battalion. This platoon‑level, turn‑based wargame is set on a hex‑based map where each turn represents about seven minutes and each hex covers roughly 300 meters. Players control either U.S. Marine forces or Opposing Forces, using an action‑phase system in which initiative—driven by morale and readiness—determines which side acts during each phase. Units have limited activations per turn for movement or firing, and available movement and firing ranges are displayed directly on the map. Combat incorporates factors such as combined assaults, concentrated fire, terrain, morale, ammunition, leadership, command proximity, and support from off‑board assets like artillery and naval fire. The game includes scenario and AI editors that allow modification of computer behavior and creation of new missions. Built‑in content consists of 15 scenarios and three linked campaigns, with scenario outcomes based on casualty levels and objective completion. Campaigns progress through connected scenarios with some continuity of units. A full printed manual provides core instructions, while editor documentation is supplied in Adobe Acrobat format on the CD‑ROM. ==Development==
