Rust is a game that Helk and Pat have been working on for us. It was highly inspired by DayZ, Minecraft and STALKER.
We haven't released an update for a while. A long while. Because we decided that we didn't want it just to be DayZ - which is what it was looking like. We knew we couldn't build big dense cities. We wanted to change direction and have the players build the world. We also hate zombies and are going to replace them with other NPCs at some point. It's not the best looking game in the world - but we're not too concerned with looks until the gameplay is fun.
So we have a CLOSED alpha here: http://www.playrust.com/. You need an alpha key to join.
