What we know about editions, DLC plans and post-launch content for Total War: Warhammer 40,000.
No trainer exists for a game that has not launched. Avoid "leaked trainer" downloads — they are malware bait.
Play the beta if you can, and learn the faction you plan to main — that is the only legitimate edge right now.
Total War: Warhammer 40,000 has not been released, so no console commands or trainers exist for the final game yet.
The Total War engine historically ships with a debug console in single-player that enables cheats — expect the same for 40K.
