[quote name='snakemaster2389']i pre-ordered this online and havent gotten an early acces code yet

[/QUOTE]
Supposedly, some Gamestops actually got their codes on cards. This seems wrong, but some people have said that they actually got calls from their Gamestop, telling them to come in and get their code.
This is a longshot, but if you live nearby your Gamestop, it might be worth dropping by, or at least calling them to see what's up. The Early Access starts March 14-15, so technically they have until tonight to get it to you.
Edit: I hate self promoting, but please read what I've posted in long text above. It'll help if you haven't played yet. The game moves fast if you're not paying attention.
I played as Cole and Paduk last night, and found that Cole is great in the beginning of matches, but not so much once the enemy team starts rushing in. The Booshka is fantastic for getting enemies around corners, since it bounces and self detonates when enemies are near. I was able to hold off Tickers from attacking caltrops for 20-30 seconds at the start, as I kept on firing it at them and dropping ammo at my feet to keep the explosives coming. I'm sure that was part luck, but if used properly you can really hinder enemy progress right away, forcing them to either shoot the barrier you're guarding, which takes more time, or go the alternate route, where hopefully your teammates are equally putting up a good fight. Also, first thing to do as Cole is try to drop an ammo box at the intersection point a the start of the match, where all 5 COG run through. It just helps to give your teammates extra ammo right away, so that they aren't going to be panicked, looking for you later when they need ammo.
Paduk has the Snub, which I found more effective than the rifle he has. Spot grenades are great when thrown ahead, closer to enemy spawns, so that you can anticipate enemy movement earlier. It's much more effective to know when a Corpser, Serapede or Mauler(s) are coming into the battle than to find out they're coming at you with only seconds to be ready for them.
The cloud of smoke you see is a Kryll shield, preventing the COG from getting to the Spawn where the Locusts are. Grenades do nothing beyond there. I threw a spot grenade through it and it immediately disappeared. Try dropping it just before it, so that the enemy is forced to run into it. It's important to note that the Kryll shield will kill you if you run into it as a COG, so be wary of it, but you probably shouldn't be that far ahead if you followed what I posted before.
