DICE have said that the beta version of Battlefield 3 isn't representative of the final game.
The company have said that the beta's purpose is to test server loads rather than gameplay, as the game code within the demo is over a month old.
General manager Karl Magnus Troedsson told Digital Spy: "The Battlefield 3 open beta is based on software that is more than one month old. We need to test the new back end dedicated server structure we've built.
"Not only have we built a new game engine, but an entirely new back end system so that everyone can enjoy the benefits of dedicated servers on all platforms."
He continued: "Just like normal procedure when releasing a game, the open beta has had long lead times due to testing, certification, and setting up. This means that the code you are now playing is actually quite early and not representative of the final game.
"We had to do this in order to have as many people testing as possible, in order to ensure a top quality experience when the game is released.
"However, we're confident in the Battlefield formula and confident that our fans will support us in order to make Battlefield 3 better."
Battlefield 3 hits XBox 360, PS3 and PC on October 28.
Classic first person shooters...
