Let me know if you want to play Banjo online - I'm still struggling to find ANYONE and I want to get this review done. Ha ha, the pain I go through for such things. Though th egame is growing on me a bit.
To unlock Insane difficulty you will have to first beat the game on Casual, Normal or Hardcore. Alternately, you can find someone who has already unlocked it and be invited to their game. Beating the game on a difficulty will also unlock any lower difficulty, so starting on Insane will unlock Casual, Normal and Hardcore at the same time.
That means if I directly play "Insane" and be invited by my friend, I choose "Hardcore" level. After I finish the game, I will unlock Casual, Normal, Hardcore and Insane achievement. Am I right? Thanks.
I have a change for your halo 3 achievement guide.
For the achievement "Spartan Officer" you no longer need to earn level 10 in a ranked playlist and 70 xp. All you need to do is earn Lt. in a single playlist. I have proof if you need it. It just happened to my friend today.
