Borderlands – What happens to SHiFT rewards once Live Gold runs out

When you run out of health points in Borderlands 2 you enter a 'Last Stand'-style mode, on your knees and able to crawl very slowly. If you manage to get a kill with your parting shots (or an enemy you set on fire/acid/shock burns down on its own) you can gain a second wind, reviving yourself with a bit of health.

Alternatively a team mate can revive you, similar to in other first person shooters (ie: Left 4 Dead)

If you are not revived in time, you will die and be reconstructed at your last New-U Station, for which you will be charged a reconstruction fee. The fee for respawning at a New-U station costs 7% of a character's money. For example, if the character carries $1,000, the fee would be $70.

As said, the first and the second weapon are one bundle, and the third and fourth weapons are another bundle. You will start with the bundle where your current equipped weapon is in. When you have equipped your third weapon, the second bundle will be equipped.

Example:

1. Weapon: Shotgun
2. Weapon: Pistol
3. Weapon: Sniper rifle
4. Weapon: Rocket launcher

You've got equipped your rocket launcher and activate gunzerking you'll take your sniper rifle and you'll have your sniper rifle and your rocket launcher equipped. If you’ve got equipped your shotgun, you’ll take the pistol as second weapon. You can change your weapon bundle like you change the weapons without gunzerking, as far as I know it’s impossible to just change just one weapon when you have all the 4 weapons slots equipped.

Using the PC version at least, you can press two number keys, like 1 then 3, you will equip the first gun in your left hand and the second in your right hand (so Right: Shotgun, Left: Sniper, in this case). I don't know if there's a way to do this on console, though.

Edit 2:

Found some interesting facts on the GearboxSoftware Forum:

From top to bottom in your inventory, weapons 1 and 2 gunzerk with each other, and weapons 3 and 4. If you only have 3 weapons, then the weapon you are holding will stay on the right, equipping the weapon 2 if you're using weapon 1, vice versa, and weapon 1 if you're using weapon 3. Switching weapon will switch your right weapon, but your left weapon won't switch.
