Anita23What is Arc Welder and Rail Driver?

Seanrock101Arc welder is the eletric shooter gun

The rail driver is the gun that can shoot through walls and leaves a blue trail

hunterIVAre these counted if you do what the description says before you unlock it? i.e. If I kill 5 enemies while at full health, when I hit 56,000XP will I have 5 No Problems?
Posted by hunterIV on 19 Sep 09 at 06:16
Seanrock101no,Well when I did these when the game first came out I couldn't so unless they changed it now you need to do them again at 56,000 exp.

Well there are only like 2 or 3 you need more than on person fore so just have a boosting buddy to help get th other lot of challenges

RhyoliticTip for Crush...

You need to damage the person before the debris hits them. I had multiple "x has Crushed himself" which didn't count for me.

At 50% regen, 100% health, you can shoot a person 8 times in the leg with the pistol. Shoot 6 times, set a Singularity Bomb next to them (making sure to be in an area with a bunch of buildings), as soon as it is set, back off and pop them twice more in the leg. When the bomb detonates, you should get the Bonus.

AC1DGro0ve 3o3Can these be done in player matches or does it have to be ranked?

MASTERCHEATZ930How do u get the blast bonus. I never saw any barrels on multiplayer maps.
Posted by MASTERCHEATZ930 on 13 May 12 at 05:35
Seanrock101I'm not 100% on this one. But as far as I remember there are gas tanks about in siege mode to help destroy the objectives.
Posted by Seanrock101 on 13 May 12 at 11:59
NickHawkeyeThere are also tanks in crash site I believe. they are big white propane looking tanks. and you can get more than 1 from each. i.e. have 2 or 3 people standing next to the tank when you shoot it and you will get that number of "blast" points

Mobius EvalonI made a fast and crude reference map for Crash Site. It has all 10 backpacks on it so it's a great place to work on all those assorted backpack challenges. I also marked the explosive barrels on the map with red dots.
