Pathogen's out now on the UK store for £12, which is honestly a little cheaper than I was expecting given the US price. I figured they'd just do what they usually do and change the dollar sign into a pound one, so I'm glad that's not the case here.
They've also added new "Into the Hive" and "Ultimate" editions to the digital store, the former being the game with Pathogen and the latter being the game, Pathogen and all the cosmetic DLC packs released so far.
Sadly the fact that they've put out this "Ultimate Edition" after this one expansion makes me feel like this could well be the one and only big piece of story DLC we get, which is going to be a little disappointing if true. I was hoping that, even if it took another year between them, we might end up getting more expansions like Pathogen down the line.
And who knows, maybe we will! But I'm suddenly not expecting that as much as I was before seeing this.
