Too Long; Didn't Read
*Infinite* is a more intelligent shooter than *Halo* has ever been before. More choices, more things to get wrong, but just as much to get right. Weapons have respawn timers, and enemy shields glow when damaged. Power-ups no longer trigger on pick-up, either: flip the switch and make the play or stash it for that opportune moment at the risk of losing it to *them*. There’s plenty to think about, too: when exactly to use it, to which target to shoot.
