There is a new trailer for upcoming FPS/RTS hybrid Nuclear Dawn which shows off the commander mode, there seem to be some elements of the Battlefield 2 system in that you can communicate with your team and observe the enemy, while there is a more traditional RTS element with base construction. It is looking very sleek.
You can still pre-order from Steam to get access to the beta ahead of the final release on the 25th September. If the promise of some RTS/FPS action doesn’t get you interested, and that Commander trailer doesn’t, then you need to check out this video looking at the FPS side of the action. There are going to be another four videos of this kind, I am looking forward to seeing what else the team has to show off.
