beginning in the campaign, I can't even get pass the space bar move outside the train - my space bar is not very responsive, nor can I tell how many times I need to push the space bar... anybody have any an idea I could try? I already tried to remap it, and the PC insisted on the spacebar...
Battlefield 3 Walkthrough
Americans and Russians collide. Our Battlefield 3 Walkthrough gets you ready for the fight with info about online multiplayer, kits and equipment, and unlockable goodies.
General Primary Weapons
General weapons can be used by all Kits. These weapons are gained by either ranking up in multiplayer or having a high score in CO-OP. The main general weapons are shotguns, but there are also a few assault rifles and PDWs to unlock.
870MCS
The M870 is an American made Pump-Action Shotgun that has been used by Special Forces units for decades. In urban environments the M870 is especially effective due to its high stopping power at close range.

This allows the PDW-R to share magazines and supply lines with standard troops while its short length and bullpup configuration allow the PDW-R to be easily operated in CQB. Though it lacks the accuracy of a rifle, the PDW-R has a greater punch at longer ranges than other PDWs.
