Welcome to Rainbow Six Vegas! This game has 36 achievements with a total of 1000. The game isn’t too difficult and all of the online achievements can be boosted with a partner(s). NOTE: You can cannot get the full 1000 if you don't have an Xbox live vision camera.
Note about the time requirement:
"Best of the Best" takes roughly 40-45 hours by itself and that's slightly low balling it. If you do the LVU campus Realistic T-hunt method and hardly fail the completion will come in at around 60-70 hours. If you choose to rubberband boost "Best of the Best" total time will come to easily over 100 hours. You may not be playing during that time but its still hours on the game that you can't play something else.
Step #1: Playthrough #1
Start by creating a character and use the vision camera to gain the "True Identity" achievement.
Since there is no achievement for completing the game on easy, normal etc. so start the game on realistic difficulty. This isn’t that hard if you take your time and use the Desert eagle and Shield combo (See achievement guide for exact locations) This will allow you to take enemies down in 1 shot sometimes 2 and the shield will give you maximum protection, also you will have full use of your team. You have to playthrough each mission from start to end as reloading checkpoints sets your difficulty to normal. In this playthrough you will also earn all mission achievements and as you’re using the desert eagle you will get the kill 150 terrorists with pistol achievement.
NOTE: You cannot get the realistic difficulty achievement in co-op you have to play single player.
Step 2: Playthrough #2 [Coop]
This will be a very quick playthrough of the game and will not take very long at all, you can do this playthrough on split screen or Xbox live. Once you have your partner start the game up on normal and unlimited respawns then proceed to playthrough the campaign, this will net you the "Vegas Champion" achievement. After you have gotten the "Vegas Champion" achievement then its time to get the "Tour of Duty" achievement. See the achievement guide for a list of maps you have to play, again use the desert eagle and shield combo set the density to low and difficulty to normal.
Step 3: Online achievements
All of the online achievements can be boosted with a friend/partner barring the "Master of Ceremonies" achievement and "Best of the Best" achievement.
If you need a partner, then check out the forums and you will be sure to find somebody. Set-up the match needed for the achievement and then have your friend search for your name when they have entered your game start it up and the person wanting the achievement will get the kills/win etc. This game isn’t played often anymore and you will have no problem finding each other.
For the "Master of Ceremonies" achievement you have to host a game where you are the dedicated server and have 16 people join then start the game. This is a very hard achievement to unlock and will more than likely require you to boost it, check the forums to join or start a party.
For the "Best of the Best" achievement you have to reach the rank of Elite This is a very time consuming achievement and the best way I have found to reach this rank is to play Co-op T-Hunt on Xbox live set the density to high and difficulty to realistic on the map LVU Campass with a good team you can finish the round in under 2mins and earn yourself 600 experience points a win.
This is not a very hard game to get 1000 in but reaching the rank of Elite will take some time. If you need any further assistance please refer to the achievement guide and forums.
