Microsoft and Sony grappled at E3 on Monday for the hearts of hard core gamers whose devotion could determine whether Xbox One or PlayStation 4 rule console play and Internet Age entertainment.

The rival console makers aimed squarely at hard-core video game players in grand press briefings, unveiling blockbuster titles and touting content or opportunities only available on their respective systems.

Microsoft opened fire with Halo and a barrage of other titles for play on its new-generation Xbox One consoles including an addition to its popular science fiction Halo series called Halo: The Master Chief Collection, as well as other exclusive titles Sunset Overdrive, Forza Horizon 2 and Dance Central Spotlight.

Sony shot back in a return salvo lead by keenly anticipated Destiny, the first new franchise from Bungie Studios revered in the gaming community for creating Halo.

"Our vision is grounded in an uncompromising commitment to gamers," said PlayStation Group Chief Andrew House.

PS4 owners will be able to play an online test version of Destiny starting Thursday and through the coming weekend.

Sony is even launching a white PS4 in September as part of a Destiny game bundle when the game is released.

Exclusive PS4 games touted included new IP The Order 1886.

Powerhouse titles heading to consoles include exciting sequels to franchises including Batman Arkham, Uncharted, Assassin's Creed and Far Cry.
