It's non-news by this point and only like 5 people care about Halo CE, but I'm pretty pleased fam.
1.5 is basically a community created Map Pack that was ported to the Xbox version of Halo (and never released on PC for some reason) that focused specifically on Competitive gameplay like a few of the vanilla maps - Something that's rarely done in Custom Edition. The makers of the map have stayed true to Halo CE's competitive Multiplayer by using the weapon spawn timing to direct the flow of each game, which has been overlooked in a lot of Map releases.
Most of the maps' gameplay ends up being too slow, unbalanced as hell, or a spawn camping shitfest that's fun for exactly 1 person on the server, even in gametypes they were designed for (I'm looking at you, Coldsnap, Extinction and Bigass). The ones that are reasonably competitive often get overlooked because of a lack of gimmicks (people love their reskins/super mega le teleport riddled blood gulch with 99999 sniper rifles xDDDDD), but there seems to be a bit of a
following with this map pack's porting on Halomaps.org.
Even with Halo PC's broken netcode interfering with online matches and altering the weapon spawn times by 6 seconds, I still hope to get a LAN community happening in my area for some competitive matches.
