My Summon Is the Astartes

This is the story of a player who travels through various worlds, loots various abilities, and then jumps up and down in the world of Warhammer 40,000. Summon the long-dead Thunder Warriors, give them the power of countless worlds, punch demons, kick orcs, tear apart zerg with your hands, blast undead, and head-butt humans! You are also loyal, why are you sent by the Emperor? I thought it was Chaos! Say it to my power hammer! I heard that there is chaos without distinction, then I am loyal without distinction I can be loyal too! Travelers are gamers, but their gaming profession is related to the Warhammer world. The main world is Warhammer, but it is not just Warhammer. I plan to write about the worlds of Avengers, Warcraft, X-Men, StarCraft, and The Witcher, and I will add more later!
