John Woo's Stranglehold explains the action game's cover system with a rather ingenious analogy: Space Invaders.
More specifically, Senior designer Patrick Curry is describing medium-sized objects (e.g. couches, concrete columns) that you can use for cover and are destructible. "As your cover shrinks Tequila will automatically crouch down to use whatever cover's left," he said, "but in Stranglehold no cover lasts forever." It was lead designer Neill Glancy who came up with the analogy, which explains how gunfire will slowly whittle down cover that either you or your opponents may be using.
We know what you're thinking: will you have the cojones to blast through your own cover, just like in Space Invaders? Real-world application of retro gaming skills embedded after the break.
