There may be 256 people playing, and they affect the outcome of the game, but you won’t find more than thirty people (and that is a generous number) on your screen at one time.
The beginning of my demo started with a helicopter base deploying my unit about a hundred yards from my squad’s objective. Each player, out of the 256, is assigned a squad with an array of tactical targets and two main objectives. These objectives give players advantages over each other, like destroying radar or building a forward outpost that players can spawn from. The main objectives alter a bar on the top of the screen that determines which side is the victor at the end of the match. The map has a great scale and the objectives are spread out to give players a bit of running room.
Honestly, there isn’t much to say about the game besides it works, and it isn’t terrible. The biggest complaint I had about the game was that there was some lag when throwing weapons and sometimes enemies would die a few seconds after absorbing a few rounds (again, the lag was the culprit)
