Zombie prison movie?

[texol]

A mate said hed seen a movie on dvd about the living dead (zombies) that take over a prison (sounded like your regular zombie infection type of thing) it was a pretty new movie anyone any ideas what it could be? Also has anyone seen Return of the living dead parts 4+5 (some people think there naff but id love to collect the full set, im a bit of a living dead movie fan) er are they any good?

It might be Day Of The Dead 2: Contagium which is set in an institution... but be warned, it's dreadful! Came out on DVD at the start of the year.

Yet to see ROTLD 4/5 yet...
