Grind looks awesome as it has since I first the DLC Announce video. I like the indoor sections and the less angular look of the pathways and choke points. The colors and inflatable, wavy tube men are really a nice change of pace. Looks like something out of Tony Hawk so I'm curious if this is one of the Neversoft designed maps.
The other map, not so much. The gimmicky chairlift looks dumb as crap.
Peacekeeper looks meh overall though the iron sights look like a better version of the Ballista's which is a good thing. It at least doesn't look terrible as I like the default look and futuristic take on what appears to be a bigger UMP. --- "Cover your receptors Perceptor." Driver picks the music.
