Infinity Ward executive producer Mark Rubin tweeted a seven-second teaser featuring what appears to be an in-game menu for “squad” gameplay in its upcoming first-person shooter, Call of Duty: Ghosts. The clip, posted below, is just long enough to give a sneak peek to “online play” and “options” menus. Just before the video cuts out, “Squads” can also be seen at the top of the screen. Rubin does not state what game the clip is from, though Infinity Ward announced earlier this week that it will unveil Call of Duty: Ghosts’ multiplayer component Aug. 14. Call of Duty: Ghosts is currently slated for launch Nov. 5 for Wii U, Xbox 360, PlayStation 3 and Windows PC. Releases for Xbox One and PlayStation 4 will follow. SOURCE: Mark Rubin...
