It's clear some developers are out for a challenge, and Iron Galaxy Studios has seemingly gone for the mission impossible with Borderlands 2 on Vita. The bedrock of any shooter should be an even and dependable frame-rate, but this port sacrifices so much in the visual stakes and earns too little back in terms of performance. Downgrades in everything from shadows, effects, textures and even its co-op player count are unfortunate, but stand for nothing when a game still runs in the 10-20fps range - with stuttering dragging it down further.
In its current form then, this Vita edition is difficult to recommend. Despite being one of the most technically ambitious ports for the system, it remains just that - a port, and one which does not seem to be the best possible hit for the Vita architecture.
