Starting this Friday, October the 15th, the Halo – Master Chief Collection will be free to play on Steam! But only for the weekend.
This will give you a chance to replay the old classics, or try out the newer games, to see if you want to make the investment. Because, at the moment, everything in it is 50% off for the weekend as well. So, if you are interested in it, now is the chance. The most expensive game in there right now is $5.50, and that is quite a steal!
Halo: Combat Evolved, Halo 2, Halo 3, Halo 3: ODST, Halo 4, and Halo: Reach, are all inside the collection, all currently 50% off, and all free for the weekend. Give it a shot! You have nothing to lose, well, except for some disk space. I know I will be revisiting Halo: Combat Evolved for sure.
You can find the link to the collection here. Remember, this is only for a limited time.
