Should you buy Halo 5: Guardians? Yes, when it has its release date for Xbox One of mid-2015.
Should you pre-order Halo 5? No. The answer for this is simple: Assassin's Creed: Unity.
If video game releases over the last few months have taught us anything it's that just because a game is anticipated, doesn't mean it'll actually work.
We got the opportunity to play the Halo 5: Guardian's multiplayer beta before it went live to the public this week and overall it looks like the new Halo game will be one of the biggest Xbox One games of 2015.
A beta however is no guarantee of success however. We've still had no chance to play the campaign and indeed there's no official release date other than 'mid-2015'.
For now then, go download the beta, enjoy it for all its glitches and then wait until the game comes out. You'll get a copy whether you pre-order it or not and waiting might just save you from a broken and angry first few weeks.
