50 Cent: Blood On The Sand

Note; This is the G-Unit achievement, it requires you to complete this mission as a member of G-Unit, you do this by playing over Xbox LIVE with someone and fully completing this mission, if you join after the start of the mission you won't get the achievement, if you're playing as 50 Cent then you won't get the achievement. Try setting up a gaming session here; http://bit.ly/dOmqeu to find someone to work on this achievement with you.

There's not a great deal in terms of what I can offer you in advice on how to get this achievement, it's already stated in the achievement description; complete said mission on any difficulty. So instead I've linked in some videos that will walk you through this mission, they'll give you helpful tips on how to beat it on the hardest setting, show you the poster/target locations, enemy locations and when to expect scenarios and how to complete them!

While this specific achievement doesn't require you to play on Hard mode, you may find it beneficial to do so and work toward this; Solution for Bulletproof In 50 Cent: Blood on the Sand while playing through the campaign, check out that solution for some specific tips on beating missions on Hard mode.

I realise these videos show you the game from 50 Cent's perspective and not a member of G-Units but the mission is the same and the videos will still prove helpful!

Complete Mission 1 on any difficulty. To get this you have to join someone's game and beat all the chapters. You will NOT unlock this if you are 50 Cent.
Mission 1 - Consists of 2 Chapters

All you have to do for this achivment and all the other G-unit achivments is be the second player in a co op game mode.
