Over the past five weeks we've been doing something a little different on Kotaku.

In partnership with Netflix and Iron Fist, we thought we'd produce an actual video game. We called it The Iron Controller.

It has finally come to this. The ultimate showdown. Mark versus Alex.

Who will prevail?

(It's also your last chance to win cash-money to upgrade your home entertainment. There's also that.)

When we last left The Iron Controller things were getting complicated. Mark was deep in training, while Alex was scheming, bending Kotaku Australia to his own, insane will.

Today, in chapter 4, Mark will finally unlock the true secrets of The Iron Controller. And prepare for the ULTIMATE BATTLE.

Now the training begins...
