Invasion is awesome, the sheer raw power of the Elites, the balance, the weapons, etc. I didn't find any problems with it, though sometimes when something had eight seconds left and the elites draining the time were killed it would reset itself a second or two but I'm not sure if this is a glitch or Spartans can actually make the time longer by standing on the objectives. Either way it's incredible and people complaining should be quiet unless they've got a reason besides hating the Beta because they have to actually think more. Although I think the Skybox should be a bit bigger to accomodate the Banshee. The only other complaint I have is with Invasion slayer, there needs to be more weapons as I had an instance where the other team had three wraiths and so my team was absolutely powerless to stop them to do not having any weapons besides the two loudouts we had, none of which had any heavy weapons.
