GB writes:"Well upon downloading and installing the Killzone 3 beta about an hour later I booted it up and was blown away immediately by the new features right off the bat. Mechs are in multiplayer and they are a force to be reckoned with. I was annihilating people in this thing with its missiles and turret gun until I was finally taken down. Jet-packs are also in multiplayer which are very fun but you can be vulnerable in them. You make think that these additions may imbalance the game. Well if you plan on taking a Mech head on then of course your going to get crushed but with the right tactics it’s not hard to take out a Mech."
