Unofficial expansion pack trailer

You want to play some Doom 3 custom maps with friends?, there're a lot of custom maps for OpenCoop 2.0 out there, like OpenCoop mappack 2.0, InHell, Make it morning , etc...
But in this mappack we have new maps and also custom monsters. And if you're a hardcore player, there would be a hard version of (almost) every map

Release date: December 24.

The Jurassic Doom 3 Park is Open

2017 and Doom 3 isn't dead yet (not at all), and I want to put my part to keep it alive with some fresh content and also some old custom maps here.
So consider yourself welcome to the Doom 3 Park.
