Microsoft's opening salvo from this year's E3 was the first full gameplay of Call of Duty: 3.

Beginning with an underwater sequence that has you sneaking up on a nuclear submarine off the coast of New York piggy-backing a ride on it until it surfaces, breaking in and stealing the launch keys to launch a strike, then escaping by speedboat.

Clearly MW3 has all the hallmarks of the series with Bruckheimer-esque sequences. The speedboat escape has your team sprinting for a helicopter followed by a hail of gunfire from Russian pursuit craft.

Impressive as it was there was little that we haven't seen from the series before but not a bad way to warm up the crowd for Microsoft's press conference.
