Century Media released a box set called "Unleashed – Immortal Glory: The Complete Century Media Years" back in 2008" which has the first 7 studio albums, a couple of live albums and rarities. It might be difficult to find a copy of it though and probably the prices are skyhigh. There's also been some decent individual reissues of the bands Century Media albums. The band is definitely worth diggin' into. Back in the day, them, Entombed, Grave and Dismember were considered the big four of Swedish death metal (they still are imo) - saw them all on tour in 2006, it was awesome.
