If you've been waiting for a good deal on Halo: The Master Chief Collection to buy it, today is your day. You can grab it from Amazon today for $30-off its regular price of $49.99.
Of course, Halo: The Master Chief Collection isn't just a game but a collection of games, as the title implies. It includes Halo: Combat Evolved Anniversary, Halo 2: Anniversary Edition, Halo 3, and Halo 4. At $19.99 for the whole package, that's $5 per game.
Due to bugs in the game's early days, anyone that bought it before December 19, 2014 received Halo 3: ODST as a free add-on. If four games isn't enough for you, you can add ODST for an additional $4.99 from the Xbox Store.
Other goodies included in Halo: The Master Chief Collection include Halo: Nightfall, a digital series and lots of other bonus content.
