Microsoft revealed its new "Halo" with a masterful tease during the June 10 opening keynote, while series creator Bungie showed new project "Destiny" during Sony's presentation.
To keep viewers guessing for a minute and a half is no easy task, but Microsoft Studios and current "Halo" house 343 Industries took a shot at it with the first trailer for the first "Halo" on Xbox One.
The sight of red-cloaked figures on desert dunes was reminiscent of Sony's touching PlayStation 3 exclusive "Journey," but the "Halo" teaser concluded with typical bombast, revealing the rugged helmet of a Spartan soldier beneath that cowl, and a towering mechanical beast before it.
Sony, meanwhile, made space for "Halo" creator Bungie on its own stage, backed by publisher Activision of "Call of Duty" fame.
Space western "Destiny" pits the last inhabitant of a ravaged Earth against strange new enemies that live outside the city's walls.
In contrast to the "Halo" tease, material for "Destiny" shows a game apparently much nearer completion.
It's to combine elements from first-person shooters with massively multiplayer online gaming, allowing players to mix and mingle as they seek to take back Earth from its unwelcome interlopers.
A 2010 contract between Bungie and Activision showed plans for a four-game four-expansion series, with the first to release on Xbox consoles first; whether still true or not, that hasn't prevented Bungie from gracing the PlayStation 4 announcement nor Sony's E3 showcase.
Having been confirmed for release on Xbox One, Xbox 360, PlayStation 3 and PS4, with a PC release mooted, "Destiny" is not to launch prior to 2014. "Halo" for Xbox One has been confirmed for 2014.
