These are minor niggles, though, because the crash and spectacle of the piece is enough to sate even the most cynical of detractors. The rattle of assault rifles and the pew-pew of the Covenant's lasers feel just as exciting when they're coming out of a portable device, and the Halo universe works brilliantly from a different viewing angle.
It won't sell hardware, but this is a rich and enjoyable arcade blaster with enough content and challenge to keep you playing for a good couple of days. The lack of multiplayer is a bit of a sore spot, but it is promised in the not-too-distant future.
Halo: Spartan Assault shows the potential of Windows-powered tablets and phones as gaming machines. Microsoft, 343, and Vanguard have shown the way - now it's up to the rest of the game-developing world to take notice.
Bright and a little bit brilliant. If you own a device that can run Halo: Spartan Assault, you should definitely give it a try
