The Red vs. Blue team from Rooster Teeth's machinima series take a look at the "normal soldiers" of Halo 3: ODST.
Their reaction was pretty much the same reaction I have to a new Halo game. I think, "Hooray! I shall be at the same skill level as many other people for a short period of time!" Unfortunately that short period of time is around 15 minutes, give or take, so the elation generally doesn't last long. After a half hour, the advanced players have already found out how to teleport directly into the game's code to attack the AI programming, while I am still trying to not sticky grenade myself.
