Borderlands and Borderlands 2 were two of my favourite games on PS3, and I was delighted when I read that 2 was coming to Vita. I can see the argument that the Vita needs new and original content, but it is absolutely magnificent to play such a great game on the move.
The reviews in the press have been disappointing, and there are a few technical reasons why the Vita version isn't quite as good as the home console ones. It doesn't have quite as many enemies on the screen at once, there are some occasions where the framerate drops, and co-operative play is only two players, not four.
Of these issues, the first is frankly a non-issue, as the action is quite frantic enough. And the third doesn't affect me at all, as I never play online. The second is something that is noticeable, but so far (I've got up to the sanctuary and done a few of the missions from that point) hasn't made the gameplay any worse.
This is a very good value package - lots of downloadable extra content is included as well. If you do have the PS3 version, Borderlands 2 has a cross-save version, so you can play on your PS3 at the weekend, and then continue the adventure with your character on your Vita on the way to work.
At under twenty quid, this really is something that every Vita owner should have, I think it's second only to Persona 4 Golden as an essential Vita title.
