7. Borderlands Co-op/OnlineUpdate notes

Co-Op

The strongest point of Borderlands is the Co-Op. Grab a friend or three (it supports up to four players), or simply find a game with other Borderland enthusiast by joining a quick match, and you can gain the following achievements:

Upon entering the Co-Op world, and given that one of your buddies already has it, you’ll earn a Viral achievement. If it doesn’t pop, set up a Gaming Session here on TSA and I’m sure someone can help out. It only takes 2 minutes.

No doubt, unless your buddy is “God-like”, he’ll die. When this happens, it’s up to you to be his/her saviour. You’ll know you have to heal them as a huge “HEAL” appears above their head. Stand next to him/her (they should be in a kneeling position) and press and hold the E button. Job done.

Everyone loves messing about in Co-Op. Trying to shoot your friends in the throat and watching them die a slow death is a temptation every gamer can’t resist. And Borderlands has taken this into consideration by introducing a “Duel” system. Melee your friend and you’ll challenge him to said duel. If he accepts you’ll both enter a small arena where you can happily shoot seven shades of red out of each other. Win one of these duels and not only will you’ll be able to rub it in your friends face, but you’ll have earned the Duel-icious achievement.

If you manage to defeat your friend without any damage, you’ll earn the off-the-record rank of “Godly”, but also another achievement. If you have a nice friend, he may just let you earn it anyway. If not, you had better plead with him/her.

After doing both of the above and you still can’t decide who the better dueller is, you can have a showdown in an Arena match. Head over to the Arid Badlands, near where T.K. Baha hangs and you’ll see a large sign with “Arena” on it. Enter the door and set up an Arena match with your buddy at the Bounty Board-style machine. Then, it’s the first to three kills, so let the duelling commence!

You could just jump into someone’s game when they’re at the relevant Bosses (Rakk Hive, the Vault Boss, Sledge, Krom and Flynt) for the next achievement. Just make sure to turn in the missions once you’ve defeated them. There is a way to do this Solo however. Defeat a boss, but don’t turn in the mission, making sure it is still active. Exit back out to the Main Menu and start up a split-screen game using the same character, then turn the mission in.
