Wasteland Apocalypse: My System Is Age of Empires

After transmigrating to an apocalyptic wasteland, I find that other Systems hand out guns and ammunition for free, while the one I awakened is Age of Empires IV, a game focused on melee weapons. How am I supposed to play this? All the summoned units are supernatural beings? Oh, in that case, no problem. A knife or a gun, what’s the difference? What kind of brilliance can the Age of Empires IV System shine in a wasteland full of treacherous people and deadly dangers? Can an utterly ordinary transmigrator really build his own super empire?
