No word on Mod support just yet. It is something we highly support and something you will see us include in future titles.

The comments are directed to a very old (nearly 2 years) version of the game. What you saw Markiplier play was the most recent public builds (which are far better - and nearly incredible if we do say so ourselves (biased).

We hope to run into you in the game!
