It's actually pretty good!
Strangely enough, this is the first shooter I've played where there isn't a bad guy. The fictional ocean city known as "The Ark" is falling apart, and it's the last known human refuge (serious flooding). You choose between two factions: the Resistance, who want to escape the island, or the Security, who want to save the island. It actually has one major positive message: fight for what you believe in. Unlike most shooters, you're not tasked with "Kill X amount of bad guys," it most always "Defend this point" or "Escort this individual." Even when it comes to the actual combat, there's minimal blood. The main draw was the parkour-like S.M.A.R.T. system, which allows for movement over basically anything simply by holding the sprint button. It's a nice feature for directionally-challenged gamers, as it minimizes needing to turn and dodge. The stylized graphics are also a nice change of pace from the hardcore realism everyone seems to be striving for these days. If you're looking for a good birthday or holiday present this is it. Just ignore the critics, they're paid to complain, not to actually enjoy anything :)
