In the grim dark future there is only war. No, really. In Warhammer 40,000: Gladius - Relics of War, there is no diplomacy system. All of that nonsense has been put aside in lieu of 40K chainsword murder. Gladius manages to be a chimera of strategy games. Is it a 4X? Part of an RTS? Grimdark Civ? Whatever it is, Rob and Fraser generally like it.
