A video got released last week that i missed.
It’s showing the progress on weapons, the Assault rifle/grenade launcher for instance.
On another topic, OT’s “lead designer” said on Epic Games’ forums that a playable multiplayer alpha should be released soon :
The first alpha is coming in one week max, it will be VERY WIP, but will have working multiplayer in a handful of maps and enough weapons to make it interesting. -vblanco, on April 28th
For people that missed it, here is the official Open tournament forums for now : otforums.varitechllc.com/index.php
