How to unlock the Hardcore Superstar achievement in NHL 10 - Definitive Guide
The key is to make sure you switch it back to Hardcore before the game ends.
From the main menu go to My NHL 10 --> settings ---> Gameplay settings. Now change the skill level to superstar. You CANNOT adjust the sliders. I would also recommend you choose the Eastern Conference All Stars vs a AHL team to make it even easier. You can also edit the players so that everyone on your team has a 99 rating and the opposing team has a rating of 50.
Set the game difficulty and the style to Hardcore and win the game. you cannot adjust the sliders in your favor when you are on Hardcore style as it will rest back to default. For an easy way to win:
Make sure on the game settings screen you slide over and change the difficulty to Superstar and the Game style to Hardcore. If you want to do this quickly, you can start a new Battle for the Cup. Choose your team as the 100th Anniversary Canadians and play against Poland. Go to the schedule and click sim game. When the Period 1, 2, and 3 screen pops up, wait until the score for the 3rd period pops up, then choose to intervene. When you enter the game, you should be ahead with about 5 in game minutes to go. Just hold the puck for as long as you can to run the clock down and bam.. 20G.
