I'd only recommend to play this comp if your first Augment is "Ravenous Hunter" that makes your Warwick into a powerful carry. It is possible to pick the Augment in Stage 3-2 and pivot into Warwick Carry, but this can be risky if you don't have the right items for him.
The core concept is very easy, you push for Level 6 in Stage 3-2 and roll for 4 Juggernaut, 2 Zaun and 2 Challenger and upgrade your board. From here you recover your economy back to 50 gold and slow roll your interest for Warwick*3.
Depending on the game state you will have to force Warwick*3 between Stage 4-2 and Stage 4-5 to stabilize in mid game. Once you have him you can push towards Level 7 and 8 and add 6 Juggernauts to make him more tanky. His item build should include one sustain item, Guinsoo's Rageblade and Quicksilver for CC immunity.
If you are only playing two Zaun then Robotic Arm is your best Chem Mod. With 4 Zaun you can give him an overcharged Shimmer Injector or Hextech Exoskeleton instead. Outside of Warwick you can itemize Silco with items like Blue, Morello, Gunblade and Nautilus with Evenshroud and Redemption.
