We saw a bit of the free-to-play shooter No Man's Land at E3. It's the first of its kind: a console FTP shooter.
No Man's Land is not a crack on PS Home. It's actually a pretty ambitious undertaking, and it might be worth checking out to see how well they were able to pull off Team Deathmatch-ing in an online world. Beyond this, you might appreciate its cover-to-cover moving system or its post-apocalyptic American setting. If nothing else, you might dig seeing your Home avatar take up guns and begin killing.
