The Merc and the Spy have been bitter enemies ever since the former neglected to hold a door open for the latter sometime in the late eighteenth century. That one act of (quite unforgivable) rudeness sparked a centuries-long feud, escalating through name-calling, to pranks, and inevitably to murder . After sitting Conviction out, the pair are at it again, in Splinter Cell: Blacklist's (opens in new tab) returning Spies vs. Mercs multiplayer mode. IGN (opens in new tab) have a video of the celebrated mode's grand reveal, and after crawling through an air-duct with a pair of night-vision goggles on, so do we. See it in action after the break.
If you can't quite cast your mind back to 2006 and to Splinter Cell: Double Agent, when Spies vs. Mercs last appeared, it's an asynchronous multiplayer mode pitting a team of Spies (sneaky, stealthy) against a team of Mercenaries (heavily armoured, and packing heat). Here the former are tasked with infiltrating and hacking terminals, while the latter are employed to guard them. You can probably imagine how that's going to pan out.
In previous games, Spies vs. Mercs was either a two-on-two or three-on-three type deal, but that's been upped to four-on-four in Blacklist. As you can see, it all looks very exciting - I'm looking forward to getting stuck in. Sam Fisher's latest jaunt is due on the 20th of August in the US, and the 22nd in Europe. I'm willing to be bet there will be more trailers in the meantime.
