After years of waiting, the newest entry in the Street Fighter series has finally come. As with every other Capcom game, this game is an extremely difficult game to max out, as it requires much skill to complete every character's combo trials.
Thankfully, a majority of the single-player achievements are easy enough thanks to Zangief. Zangief has an attack called the Double Lariat, which you can easily spam against the computer without too much trouble. Thanks to this skill, you can easily beat arcade mode on the hardest difficulty, and get gold medals in all of the time attack and survival challenges.
Depending on your skill level, the multiplayer achievements will either be easy, or a nightmare. Veterans will have no problems due to the amount of new players online, but even if you don't have enough skill, you can easily boost them.
Step #1: Arcade
The first thing you are going to want to do start on completing Arcade with everyone. Set the difficulty to Medium, 1 round, 30 seconds, and start going through the list of characters. If you have trouble using a certain character, start Arcade up with Zangief. Proceed through the Arcade until you get to Seth, and lose. From there, you can switch to whichever character you need to complete Arcade with.
Seth is a difficult boss fight, as many of his moves will have a higher priority than yours, and he will constantly teleport around the arena, making it difficult to keep track of him. The key to beating him is wait for a chance to strike, do a few hits, and get away. If you become greedy, Seth will punish you for it.
Step #2: Challenges
Challenge mode consists of Time Attack and Survival, which are both self-explanatory. The best way to go through every challenge and consistently get gold medals, is to use Zangief. Using his Double Lariat, you can easily get though all of these challenges, just be ready to guard. The only thing you have to worry about is Cammy, as the computer will spam her Spiral Arrow attack, which will go right under Zangief's Lariat. You will need to be a lot more defensive against her, hitting her mainly with focus attacks.
On top of Time Attack and Survival, you also have every character's trials. Completing them will automatically give you a gold medal, but the later ones will heavily rely on your skill. There are numerous videos showing how to them, but it is still difficult.
Step #3: Multiplayer
Every multiplayer achievement in this game can be boosted, making them extremely easy to complete. If you need help finding a boosting partner, visit the achievement trading thread, right HERE.
Conclusion
Street Fighter IV is not for the feint of heart, as the character trials will drive you insane, if Seth doesn't do that for you already. If you haven't played an previous incarnations, be ready for a huge shock at the difficulty of the game.
