I was the lead lighting artist for Killzone Mercenary (2013) on PSVITA. M06 was our initial 'Visual Benchmark' level where we pushed our art and tech as hard as we could for the hardware. We ended up getting the game to look a lot closer in quality to a full console game than we first thought would be possible. This was despite the hardware running on about 2.5Watts compared to up to 100W for a home console.
