This is the collector's edition that includes a vinyl record in addition to the fancy packaging and contents. It's in keeping with the game theme, but not what I would consider a desirable collectable compared to figurines of other games.
The other two stores that had it reduced prior to Games reduction were Play and Shopto.net. Both of these competitors are priced over £25. Could hold out and see if they match this price or reduced it below £17.99
12 Vinyl LP with BioShock orchestral score
Audio CD with BioShock 2 orchestral score
Three vintage Rapture advertisement posters (rolled)
BioShock 2 Art Book, 164 pages and hardcover
BioShock 2 game
There is no demo available for this game from what I can gather.
Not sure if offer is available in store.
