Finally finished Tier 1 mode and got my gold trophy, it was the most intense game mode i have ever played. If you die you have to start the level from the begining, so you have to play it safe but do it fast so you beat the par times. To tell you the truth i had to finish some levels 3-4 times to beat par time and the last level about 10 times. Only two trophies away from my platinum again, hope to get it soon and sell the game although i love the game i think Bad Company 2 is better.
Happy New Year :-p
