For those that played Insurgency, welcome to the new game, written using the Unreal 4 Engine.
Video is someone recorded it for the reviewer. It may look twitchy but it is just the play style of the player (not a reflection on the game)
Insurgency: Sandstorm is an unforgiving multiplayer game in which a single bullet is often lethal - even after it has passed through a wall. It is dipped in the blood of veteran military shooters - like Ghost Recon, Rainbow Six, and Spec Ops - which means that it feels remarkably familiar, like slipping on an old pair of khakis.
