Reborn as a Tank [A Tank LitRPG]

Dying is easy. Becoming a magic-powered tank? Not so much. Arthur used to be human. A fairly normal guy with a family, maybe a dog… or was it a cat? The details were kinda fuzzy. His memories didn’t handle death all that well. The darkness trying to consume him certainly didn't help. He got better, though. Sort of. An entity calling itself the Vanguard System offered him a second chance. Unfortunately, it didn't bother to explain what this new life would look like. Now, reborn as the Vanguard’s Warrior, Arthur became a tank. A real war machine, complete with a cannon, heavy armor, treads, and even a machine gun. With this new body, he must face demons, dying worlds, magic, and the not-so-mysterious Vanguard organization. All in all, not too bad for a second life.  It definitely isn’t boring. “Wait. What do you mean I have no ammo?” What to expect (Beware of spoilers):-An MC that is a magic tank-Mech transformation-Weak to Strong -Upgrades, lots of upgrades-Visiting different worlds later on-Evolutions, armies, and massive battles -Big Mechs vs Kaiju fights in the future-No Harem or planned romance Warning: This story features a mech form the MC can use for a very limited time (a few minutes), with a cooldown (over a day).
