Blacklight Tango Down

I can now confirm that this achievement is for reaching Rank 38.

Rank 38 is 230000 XP.

Just keep playing. After less than 3 full days I reached 30 with no specific goal in mind, other than to play with my friends.

If you want to level faster, and you don't care what you play, I have noticed several things.

Team Deathmatch gets you 100xp per kill, and 25xp extra per headshot.
Last Team Standing gives (if I remember correctly) 150xp per kill, and 50xp per headshot.

These two seem to give the most xp for your kills, but thats because killing is the goal of those gametypes.

I am fairly certain you get xp for canister captures and CP hacks, etc. But if you just want to kill your way to the top, then try to focus on those modes.

Another way to level faster is to obtain awards.Theres Bronze, Silver, and Gold. You can guess which gives the most xp, Bronze being the least, Silver the middle, and Gold the highest.

Each award has all 3 levels of Bronze, Silver, and Gold. When each milestone is reached xp is given, as well as the occasional Weapon Tag.

Some easier to work for awards are (Please note that I will list the stats I can see from what awards I have gotten. Some I already have Gold on, meaning I can only tell you the Gold standard, as it no longer shows the goal for Silver/Bronze. Others I haven't yet obtained any medal on, meaning I can only tell you the Bronze. If anyone can contribute extra info please message me with the standards, or comment with them below. Some stats are from memory, and may be off. Please help me to correct them if that is the case):

Yes, this game DOES reward teabaggers. I know that some will have a problem with it, but if you want to level faster it helps.

Thats all for now, if you want to see the rest you can check your Awards and their status of completion in the Field Locker, which is found right under Armory on the main menu.
