Xbox users may have to wait for the Halo: Master Chief Collection and the Halo: Reach some more.\r\n\r\nApparently, the developer hit a snag after adding the Unreal Engine 4, along with an overhauled progression system. According to the report, the additions are maxing out the memory for the Xbox consoles.\r\n\r\nMichael Fahrny, the MCC senior producer, admitted as much as he called the problem they\u2019ve been trying to address as \u201cunique.\u201d He said it\u2019s quite a challenge to run the game within the memory constraints of the console.\r\n\r\n[embed]https:\/\/www.youtube.com\/watch?v=ZDvYJGquXgE[\/embed]\r\n\r\nHe said their developers have been hacking at the problem for the MCC for a long time now. The developers are \u201cmaking good progress,\u201d but there has been no breakthrough yet. He said they have yet to find a magic bullet to solve the problem, so they are resorting to trial and error.\r\n\r\nThe developers, he explained, are trying to experiment with different approaches to see what works. They will continue to iterate until the Master Chief Collection will work as originally intended.\r\n\r\nFor the limited memory on the console, he told Tweaktown that they have to revisit each of the game on the console. They need to find out if all the memory constraints are still aligned with the final design.\r\n\r\nAdmittedly, while they are making good progress, the memory situation for Xbox is \u201cdire.\u201d That\u2019s the bad news. The good news is that it doesn\u2019t suffer as much glitch compared to the UI framework. The problem is they are trying to fit a square peg in a round hole. Some of the content is simply not natively designed into the game, so they need a lot of tweaking to make it work.\r\n\r\nThey have devoted an entire team as testers. Their only job is to run a pulse to get an idea of the total bug count, the issues that are causing these glitches, etc. While the bug count is not as many compared to the UI framework, each bug is complex. While he admitted that the challenge appears insurmountable, they are moving in the right direction.\r\n\r\nThat probably means that the Master Chief Collection probably won't arrive on the Xbox this year. It also means the release of Halo: Reach will be pushed back even if they are gearing to test the PvP on Reach. But then again, the developer has not given any estimated time for the testing flight.\r\n\r\nWatch out for more news on the MCC and Halo: Reach, which will be posted when they come along.
