Blacklight Tango Down

For this achievement you'll need to reach level 70 which will require 900,000 experience. There's no quick way of reaching level 70, you'll need to invest a lot of time and patience into this achievement even if you're boosting.

How you decide to play is entirely up to you but seen as the online modes to this game are nearly dead I recommend that you consider boosting for the experience.

To boost you'll need a minimum of 6 players as the lobby won't let you start up a game until you have that number of players. There's no way of playing in a private lobby and so when boosting it's more than likely that a few random gamers will find your lobby and disrupt your boosting party. It's best to try and explain to them that you're only boosting and ask them to leave, if they refuse to leave then switch game modes for a little while to try and get rid of them. It's also a good idea to set yourself to appear offline while boosting as this will prevent any of the random gamers from going to their "Recent Players" list and clicking to "Join game in progress" from your profile.

Now, as for the actual boosting methods. The most efficient way to boost this in a group of 6 people is to play "Domination". In this game type you're tasked with hacking each of the maps control points and holding on to them to win. Now each map (bar one of them) has 3 control points in it, which makes this method ideal because no-one will have to sit around and wait for their turn.

Domination Boosting:
In the game lobby have 3 players set their clan title to "ONE" and the remaining 3 players set their clan title to "TWO". The names aren't important and feel free to change them to whatever you like, but they're cap-sensitive so make sure each "clan" has exactly the same tag. The reason we're doing this is because the game will recognise the clan tags and always group you together with your clan.

When the game starts each of you need to head to a control point each. Once you're at the control point there should be 1 player from each clan, if there are 2 members of the same clan there then 1 of them needs to move on and find their own control point.

Now the next step is down to your preference. You can choose to simply hack the control point backwards and forwards. This will net you 100xp every 20 seconds or so or you can add in kill patterns by playing like this:

Clan ONE player hacks the control point, Clan TWO player kills him and then hacks the control point. By this time Clan ONE member will have respawned and made their way back to the control point. They then kill the Clan TWO player and hack the control point.

Repeat that process through the game and you'll receive a lot more experience. 100xp every time you hack the control point, 50xp for every kill you get and an additional 10xp if you kill with a headshot. Using this method it's easy to get 17 rotations for every player and that will work out as close to 3000xp per game without taking into consideration end game bonus experience.

An important part of this method is always using the same control point throughout that match. For the entirety of a match you only hack the one control point, working on Hack the Gibson in Blacklight: Tango Down drastically reduces efficiency and you'll end up with much less experience per game.

Now, while this method of boosting is great there are 2 maps it doesn't work on, here's why:

• Slum Lord: This map only has a single control point. When it comes up it's a good idea to let every hack it in turns toward their Hack the Gibson in Blacklight: Tango Down and from their just pair up and take turns killing each other. You can quit out and lobby up again, but that's down to you.

• Derailer: Now this map does have 3 control points but 2 of them are stationed on the middle of the subway tracks each side of the map and to make things worse, the map is very long. There's some easy workarounds to continue your boosting on this map. You can either pair up as usual and carefully hack the control points on the subway tracks, not killing each other to prevent the long run back to the control point or you can meet up at a agreed area of the map and just trade off kills.

Alternatively there's an interesting exploit that awards you experience to team killing. Have your team member jump up on the side of the bridge (right at your spawn) and shoot at them, while shooting at them have them walk off the bridge and as they die you'll be rewarded as if you just killed an enemy. If you plan on doing this I advise you at least rotate it every 10 kills allowing each player to get a "Godlike" streak and the bonus experience that comes along with it. Both team members will be able to get 20 kills using this method once they know what they're doing and this will result in up to 4000xp for the game.

You can also do this in "Team Deathmatch" mode with a friend, use the exact same method when "Derailer" comes up. Bear in mind that this will likely annoy any legit team mates you have and may also result in the opposing team quitting the match out of frustration, if they do quit the match will end early but you'll be rewarded all the experience you earned up until that point.

Here's a list of maps the "Team Kill" method works on and where to do them:
• Derailer: Use the side of the bridge inside your spawn point. One player shoots and the other walks off the side of the bridge.
• Sky Fire: Use one of the railings close to your spawn point. Once player shoots and the other walks off the building.
• Wharfare: Use the edge of the map close to or inside your spawn. One player shoots and the other walks off the side, into the water.

Lastly, this achievement is only related to your level. Once you reach Level 70 you'll have unlocked all the items needed for this achievement. You do not need to fulfil any of the "awards" for this achievement.

Note: It appears that for some the achievement doesn't unlock once you reach level 70. If this happens to you there's an easy solution to fix this.

From the dashboard go to the "My Xbox" tab and scroll to the end and select "System Settings". Now press "A" on "Memory" and then "Y" on your Hard Drive. From here all you need to do is select "Clear System Cache" and when it checks that you are sure, say yes. Doing this will not wipe your save files, it will only remove the game updates.

Once you've done that you just need to start Blacklight: Tango Down up and download the patch again, when prompted to "Press A" just before the main menu sign out of your profile and sign back in again. Do this and the achievement will unlock.
