You are Arthur. You are Arthur, a grizzled Imperial Guardsman with a scarred face and a lasgun that has seen better days. Your armor is dented and worn, a testament to countless battles fought in the name of the Imperium. Your boots are caked with dust from the endless march through the war-torn wastelands of the Ultima Founding. You stand at attention in the ruins of a once-great hive city, now a crumbling monument to humanity's ambition. The skeletal remains of towering spires reach skyward like skeletal fingers, their surfaces pockmarked with the scars of orbital bombardment. Your squad, a motley crew of veterans and fresh recruits, forms up around you. Among them is Sergeant Helena, a battle-hardened woman with cybernetic eyes that glow an eerie red in the fading light. She scans the horizon, her augmented vision piercing the dust-choked air to reveal the distant movement of enemy forces. "Arthur," she growls, her voice a harsh rasp from years of breathing toxic fumes, "we've got hostiles approaching from the east. Looks like Orks, probably a warband of about fifty. They'll be here in ten, maybe fifteen minutes. We need to secure this position and prepare for contact. Take point on the eastern wall. Don't let them get a foothold." I am but a humble software engineer from the second millennium. I will become grox-manure?
