Splatoon might look all cutesy and approachable, with its turf wars and stylish squid kids. (And no, that’s ink, not blood.) And sure, it’s a lot less brutal than Call of Duty. If you jump in thinking the single-player campaign was enough of a tutorial, though, you’re in for a rude surprise. For as casual as Splatoon is, it’s a sweaty, unforgiving series that happily stomps newcomers into the ground before they have a chance to learn. Enter Splatoon Raiders, a game that, despite ostensibly being single-player (unless you want to play co-op), teaches you a lot of the skills you need to succeed in Splatoon’s standard Turf War mode.
