No problem, we got you covered! For just $1,999.99 You can buy a season pass and download all of the stuff we didn't bother putting into the game because we could simply charge for the content later once you get bored of the initial few maps!
On a serious note, I finally have the jet pack thing and the homing missile but I want more.
The Jetpack is a staple in my card hands. I was using the homing missile but I got really good with the sniper rifle. Also, I have been playing with the barrage. Just a word of advice...once you find a card weapon you like...upgrade that sucker. It does make a difference.
In terms of trait cards...I think I have all the ones I want unlocked. My favorite trait is the bounty hunter one because small kill streaks can give you random power ups without having to search the map for them. It's awesome and it's come in handy SOOOO many times. You can't get vehicle powers ups or hero powers ups that way but I see them often enough on the map so that it doesn't matter.
