Warface

A man in a military uniform and hat shouts intensely at another man in a similar uniform, his mouth wide open and eyes wide, before his expression shifts to a more controlled, stern look; the scene then cuts to a different man in a military uniform looking forward with a neutral expression. The setting is an indoor military facility with white walls and fluorescent lighting. The sequence ends with a green, one-eyed animated monster screaming with its mouth wide open.
