BIGGEST IS BEST AND GETS MOST RATIONS!
(Ogrynheimer)
I BECOME DEATH SAH. DESTROYER OF WORLDS SAH. (Very solid build. Huge survivability pared with some nice explosions. The grenade can also be used for a good "reset" button in fights)
(Point Blank Ogryn)
OGRYN HAVE BIGGEST GUN. OGYRN SHOOT ALL THE BAD BOYS! (This build is for MAXIMUM gun. It is fun, and melts everything.)
(Pickaxe Ogryn)
CHARGE THE ENEMIES AND SMASH THEIR HEADS IN (Rush the enemies and smash them with the pickaxe. I've seen builds that go on the left side for stronger melee attacks, but this isn't actually necessary if you're using a high roll pickaxe. Even without the heavy attack keystone you can still one-shot Crushers/Maulers on T5.)
(Charge Ogryn V2)
STAB STAB STAB!. HAVE KNIFE! STAB FOR EMPRUH! (Plays similar to the pickaxe build, with node changes due to the weapon choices)
(Protector Ogryn)
PROTECT LIL 'UNS!. LITTLE MEN UNDER ATTACK. OGRYN BREAK THEM AND THROW THEM UPON THE ROCKS. THEN THROW ROCKS AT THEM. WE ARE WINNING YES! (If you use the shield you don't really need the actual taunt ability as long as you have the perk "Attention Seeker". This is because blocking the bullets counts as blocking them, so they focus on you anyway. You could go charge instead of taunt if you wanted.
BIG ROCK AND BIG BOOM. OGRYN IS BIGGEST! BIGGEST GETS BIGGEST WEAPONS! (The "Big Friendly Rock" is very satisfying, and is an excellent tool to dispatch snipers and charging mutants. The recharge ensures you very rarely run out if you use them just for sniping. If you use "Loyal Protector" or "Point-Blank Barrage") you can also grab "Frag Bomb" which is a good tool for resetting any bad situation. The entire room goes big boom, and Ogryn brain and human brain alike get happy.
