Far Cry 2

Search for and play a match in the ranked games in Deathmatch, Team DM, Capture the Diamond, and Uprising respectively. You do not have to win, only play from beginning to end.

If you're getting this achievement now days, you're going to have to boost it. Luckily, it's very easy, you'll just need a friend or a second Xbox with a dummy account.

Go to multiplayer > ranked match > create match. Choose whichever game mode you want to do first, then change the map cycle to Last Bastion four times (so Last Bastion is on the map rotation list four times). Change the minimum players to 1 or 2, and then launch the match. Invite your friend and you're ready to go.

There are four game modes that you need to play (you don't need to win the games, just play them until the end). These game modes are:

Team Deathmatch - 100 kills to end the match - Here I would just suggest starting the match and then AFK until the end, however you could boost some of the weapon manuals at the same time if you like.

Deathmatch - 25 kills to end the match - Here you can do the same thing if you want; Start the match and AFK. However it will be much faster if you get 25 kills to end the game. Meet in the middle of the map and kill the other player/dummy 25 times. This way you will also get progress towards the weapon manuals, so it's a win-win.

Uprising - Capture all 3 points and kill your friend/dummy to end the match - This one goes really fast. Just capture all three objectives and then kill your friend/dummy. Your friend/dummy should stand next to the objective they spawn nearest (either A or C), and wait there so you can kill him right after you capture the last objective.

Capture The Diamond - Capture the diamond 5 times to end the match - Very simple and quick. Just run to the enemy base, grab the diamond and then capture it 5 times.

After the end of every match, your friend will stay in the lobby and you can go to match options in order to change the game mode, so you can set-up the games very quickly. Should take about an hour maximum. Also if you really want it done quick, you can do the USB trick in order to play custom maps on ranked matches. Check the solution for "Soldier of Misfortune" for more info.

Hope this solution helped!

At the moment, i have been searching for ranked games but as of 2010 it is "deserted".

Luckily for me i hada spare xbox in my house connected up...skip the details...creating a new xbox live account will give it gold for a month, (Unless you've already made 3 profiles use this freebie) use this to get achievements or use a friend.

Works for all ranked match achievements or if you just want to complete weapons manuals.

Matches can be started with just 2 people.
