Any powers that you buy while playing a UGC mission won't reduce your XP! Just create a blank UGC mission and start playing it. Then upgrade your powers and quit the mission. You will have the same XP as you had before buying the powers but all powers will be unlocked!
Start the game's mission editor and move your marker to either of the bridges connecting the first half of New Marais to Flood Town. Raise up the marker to at least 50 feet higher than the raised bridge. Once that's done, exit the mission editor and Cole will appear where you placed the marker when you exited the mission editor! You can then use your thrusters to make it over to Flood Town!
I know how to snipe militia and monsters. I'm going to teach you. When you are about to defeat the militia and go into "kick-butt" mode hold up! First aim to shoot a grenade or shot. (I prefer the shot not grenade your choice) then aim at there head to kill them they'll go looking for you. Then it's time for you to get busy. Shoot at all there heads and your done!
Just after you use the transfer device when you're in the mission "Storm the Fort", you will get a bonus XP of 100. After you get the XP, jump into the water on your left and die. You will respawn at the same point and you can repeat to get the 100 XP again. Do this as many times as you want for 100XP a pop.
Use the magnum bolt or rocket to do more damage to a devourer - this will make defeating them much easier.
First, you need to complete the story twice. Do it once with the Hero route and then a second time as Infamous. It doesn't matter which one you do first. Wait until the credits end after your second completion, and you'll see a message. The message says that you've completed both paths and you now have access to opposite Karma powers of Cole and the other character. You also get 15k XP.
