Fector's Challenge

Journey of the Prairie King, start to finish, without dying once - the hardest achievement in the game by a distance. One clip, no continues, ~45 minutes of concentration on the Saloon's arcade cabinet.

The consensus approach: grind normal runs first until clearing it (Prairie King) is routine, because you cannot brute-force this one. Movement is everything - circle the arena edges, never get boxed in, and treat powerups as panic buttons rather than bonuses. Buy the movement boots first at every shop, then gun speed. The screen-clear nuke is for boss adds and the moment a spawner overwhelms a corner. If a run dies in world 1, reset immediately and reset your nerves too.

No tricks, no cheese on current versions - just practice. Budget several evenings, and when it finally pops, savour it. You've earned the hat. :)
