9lives.be: Mike Glosecki, executive producer for Command & Conquer 4, showed a beautiful pre-alpha demo for the game. This not only showed several units in action and the three classes, but also revealed something about a new concept in the game.
Kills and objectives will give the player XP, which can unlock certain units as you play the game. One does not have to focus on the singleplayer or the multiplayer get this, as XP is received from both and works for both. That way you can get a lot of XP in multiplayer and unlock units you can use in your singleplayer campaign. This might result in you starting the singleplayer campaign with the best units available. Keep in mind that the computer will react accordingly, resulting in a fiesty opponent from the get-go.
More information on the game can be expected in a more elaborate special on 9lives.be, soon.
