Anybody have any good or interesting suggestions for getting ready for H4 as far as skill wise?
One video said to play all the original titles, read the books and work on techniques in H3 and Reach.
But obviously that can only take you so far since H4 is going to be a different game.
Play Halo 3 and Reach. Use precision weapons all the time. And learn to use every weapon well.
Also, watch a lot of gameplay videos on YouTube, they give you some awesome tactics you can implement into your gameplay! But pay close attention.
Good luck. 
I’m working all summer at my local auto shop and partying at night.
Oh, you meant video games?
Lol implying I have to practice to be in the top percent of H4 players.
