A bit of trailer trickery might have you thinking that Crossfire: Sierra Squad is more open than it really is. While it's not quite a rail shooter, the environments and scenarios are much smaller than you might expect. Still, a wealth of content and a ton of weapons make up for the surprise once you settle in to the fact that this is an cover-based arcade shooter above all. The guns feel good, the graphics are fine, and if you turn off your brain you'll probably have a pretty good time.
