Thanks to Fips for pointing out that IGN have a hands-on article on Micro Forte's Citizen Zero from the E3 conference... "CZ is Player versus Environment (PvE) oriented, and it uses "instances" for its missions. You won't be competing against other groups to kill a specific bad guy or get a specific item, as instancing transports you into a closed environment populated only by non-player characters and your teammates....
With the instancing system reducing griefing and friendly fire currently disabled except for grenades, the game is pretty low on the frustration meter. It plays like Halo, with two weapons, two grenades, and progressive shields, but the class system definitely differentiates Citizen Zero."The article states that an open-beta won't be out anytime soon (next summer), and the new details revealed have had a somewhat mixed reaction from the Citizen Zero fanbase...
