The Battlefield Interim (04-05)
While this seemingly unheard of title didn't necessarily offer up anything in specific that had never been seen before (except the in-game commentary) as far as FPSs are concerned, The Chronicles of Riddick: Escape from Butcher Bay had an extremely healthy mixture of conflict styles, ranging from the typical shoot-em-up encounters to stealth attacks and hand-to-hand combat. Despite of the lack of multiplayer action, it was praised for its jam-packed single-player campaign.
The Chronicles of Riddick today: After being dropped along with several other titles by Activision Blizzard, The Chronicles of Riddick: Assault on Dark Athena has continued to be developed by Starbreeze and Tigon studios and will be published by Atari. The second Riddick release is now expected in Q2 of 2009.
Battlefield is also known for being extremely balanced in its destruction, utilizing a system where-by every weapon in the game has a counter weapon.
Battlefield today: After five PC titles, two on consoles, and a similar number of expansions, the series is still rolling heavy with a cartoon-style shooter expected sometime in 2009.
