Welcome to Pro Evolution Soccer 6. This game has a total of 23 achievements. A minimum of 1 playthrough is required for this game but there are a lot of leagues to beat, so a lot of time will be needed to be put in to beat them. For an early 360 game it’s pretty enjoyable and the achievements are pretty easy.
Step 1: Online Achievements
There are 6 online achievements and I would start by getting these first as the method is pretty simple and only takes around 4 hours of boosting for the achievements yet surprisingly this game is still pretty active online but the people that play are very experienced and if you're a first time player you will end with more loses than wins. So I suggest that you use this method of boosting if you want the online out of the way, First off start by finding yourself a boosting partner in the forums. Then all you need to do is set up an online Ranked match and have your partner search for your gamertag. When he/she has joined, pick your teams etc. and start up the match. Then when the match starts up one of you quits to the dashboard as you can't just back out to main menu then reload and repeat.
NOTE: The person not getting the achievement backs out to dashboard.
Step 2: Offline Playthrough
NOTE: Set the game time to 5 mins overall and put the difficulty on Easy and save after every game if you think you're going to have difficulty beating the opposition.
All in all there are 10 leagues and 7 cups to beat. Start off by playing all the Cups first, these are very short and sometimes you can edit the teams so there are only 3 teams participating so they shouldn’t take very long at all. Once these are done move onto to the league achievements.
Now this is where a big portion of the 30+ hours comes out as in most leagues you are required to play the same team twice. Start off with the Master leagues D1 and D2 As you need to playthrough them in order to get a shot at the Cups for the achievements. Be careful as you can miss these achievements if you lose the Cup game and you will not get another shot unless you start the league over again then beat the International league. These are faster than the other leagues and don’t take up as much time.
Now onto the other leagues, if you're not a big soccer fan then this is going to be extremely boring and repetitive for you. All you do is pick a league it doesn’t matter which ,each of them take roughly the same amount of time to beat, and your preferred team, again it doesn’t really matter what team you pick as the difficulty is set to easy, and you will walk all over the opposition and just play through the league. Once you get to the end of the league or you are X amount points clear of the opposition the achievement should pop.
That’s it! The game is extremely easy for achievements but require a lot of time and dedication to achieve the full 1000 as it is very repetitive . If you need any further help Refer to the achievement guide or forums.
