Halo Developer 343 Industries is currently porting the Halo Master Chief Collection, which combines the previously released Halo series with the XBOX, to the PC in addition to developing the next-generation console Halo Infinite.
Currently, Halo Rich, Halo 1, and Halo 2 have recently been ported to the PC version, and have been upgraded in terms of resolution, various functions, and technical features to meet PC users.
However, the release to PC is not going faster than expected, and on the other hand, it takes a long time to demand the patience of gamers.
However, it seems likely that the third episode can be seen a little faster. It took about 2 months to wait for the first episode on March 3 and the second on May 12, but for the third episode, the test is currently underway, and it is possible to meet in early June.
Since there is news that internal partners are currently testing gameplay, it is highly likely that a long wait will not be necessary.
On the other hand, if the third episode is released in June as expected, there are now two remaining Master Chief collections, only Halo 3 DLC ODST, and Halo 4.
