Go to the above link and watch the video of Raiden (2nd one) and at around the 3:15 mark Seth Killian says a metal gear stage will be showing up. Man I cannot wait for TGS!
Nice to hear more surprises on the way! it will be very interesting to see what the final count is when it all said and done, every stage thus far looks awesome and fun to play.. mashing up stages is a brilliant idea and gives multiple franchises a chance to shine on 1 stage. Can't wait to see more!
Couldn't agree more, now we have raiden and a metal gear stage, all thats missing is snake. Hopefully TGS will give us some fantastic news!
