Must-buy for complete experience
Bioshock Infinite was amazing in itself. The storyline is however continued in Burial at Sea episodes 1 & 2, which are very worthwhile experiences. They do provide a connection to Bioshock 1, but perhaps more importantly continue the storyline of the main character(s) from Bioshock Infinite. The two DLC episodes could be purchased separately, but the Season Pass tends to be more affordable. The Clash in the Clouds multiplayer content is also included, but thats take-it or leave-it..
