Even if you aren't sold on this Metal Gear Online trailer after a few minutes, just hang in there. We don't know why you wouldn't be excited though, what's both on display and implied in the trailer is pretty cool. It appears you'll be able to tell the location of teammates who are in trouble or just needing backup, whether or not there are walls in the way. It looks neat, but that sort of teamwork-encouraging stuff may not be up your alley.
What will be up your alley though is that last five seconds of this trailer, which we don't even want to describe for you for fear of ruining it. Let's just say it's like a carnival ride, but at the end, there is likely death. Yeah, you should probably just go watch.
