You should see the icicles we're getting around here, one goes all the way to the ground. You should also see the map Ice Fields, if you haven't lately, or ever, it's got a great ambiance and the ice cave in it is gorgeous, especially once the carnage gets going.
A good chance to see some nice ice in Halo would be at Customs Night. We've got Sidewinder, Ice Fields, Lockout, Containment, Snowbound, and more. Customs Night, of course, is a weekly get-together held in Halo where we play custom and standard gametypes on custom and standard maps.
We're finally starting to build a good base of custom maps to run, but compared to previous games, and given what's possible in the Master Chief Collection, it's just the tip of the iceberg. Customs continue to have no noticeable issues other than game chat not working and some hit detection issues in Halo 1 and 2.
It all starts Friday at 9:00 PM EST and runs until we're tired of customs. Hosting will be Gnrl Vagueness, iHyokin, and probably ShadowoftheVoid.
If that sounds (ahem) cool to you, why not join us? To do that, all you have to do is notify us, preferably by replying to this post, but you can also message us when we're on XBL. Our main rule for playing at Customs Night is "don't be a jerk".
I hope we'll see you there!
