Is halo 3 odst worth buying?

[Charles]

Is it fun i heard its too short and whats firefight? Does firefight have online play? And i heard it has 2 cd's what are they?

Halo 3 ODST is a short campaign but offers a really good firefight game type.
FireFight does have online play
and the 2 cds- ones Halo 3 for the 3 new maps, Long Shore, Heretic and Citadel
the other cd is the actual Halo 3 ODST cd

The main campaign of Halo ODST is good, but on Heroic difficulty will take less then 5 hours to beat.

Firefight is interesting. It is a take on the Horde mode of Gears of War 2. It can take much longer and as you advance it adds "Skulls" to the mix, by making it so enemies have overshield, you have no aiming, etc. Firefight is intended to be online primarily.

The second disc gives you the Halo 3 map packs, Legendary, Mythic, etc.
