Immortal Redneck

If you've reached at least floor three on the previous run, I HIGHLY RECOMMEND paying 10 gold for the Déjà Vu scroll for your next run, as your map will already be revealed; and make a bee line for the staircase rooms.

Try and be as efficient as possible killing enemies, don't stop to open chests or complete challenge rooms, and get to the Pharoah's location ASAP using your map to plot the fastest route. With practice, the first couple of floors can be cleared in three to four minutes each.

Pharaoh can be found at the end of level three in the first pyramid. He is unmissable, as his room replaces the usual spiral stair room to the next floor.

To kill Pharoah, take your strongest or fastest weapon and start blowing up the sarcophagi around the outer edge of his arena. After you've taken out six or so, the remaining ones will become indestructible, and at this point you can concentrate your fire on the Pharoah himself.

Little baby mummies will spawn from the remaining sarcophagi at regular intervals; they are easily killed and are your only source of ammo for the rest of the fight, although they won't drop an ammo crate every time.

Make sure you do some classic Unreal strafing around the outer upper edges of the room whilst shooting Pharoah, as his fireballs are easily dodged and the baby mummies can be picked off too.

When he dies, the staircase will appear - sprint to it and hit 'Y' and watch the cheev unlock!

Use a timer on your phone to time the run from when you initially spawn in the first room.

Here is how to get the Easy Peasy Lemon Squeezy achievement which i found the easiest way to do this in video form!
