Call of Duty: Black Ops 4
The launch trailer for Call of Duty: Black Ops 4 came out today. I mean, the game is out on October 12, 2018 so having a launch trailer now isn't exactly out of the ordinary.

It's a launch trailer. It shows off some scenes of action, it has some voice over work, and the like. Since Black Ops 4 doesn't have a single player campaign, you really don't have to worry about seeing any spoilers here, so that's a plus, right?

However, there are still some secrets hidden in the trailer. Charlie INTEL notes that the launch trailer gives you a little look at two previously unannounced multiplayer maps.
In the trailer, starting at the 0:36 second mark and the 0:40 second mark, there appears to be new MP Maps shown in action. One of the maps appears to be along a river, while the other is with blue buildings.

They continue on to note that there still isn't clear details on how many maps there will be in Black Ops 4 at launch. At present, there seems to be 11 maps announced, four of which are old maps repurposed for Black Ops 4. Plus, there is also the Black Ops 4 version of Nuketown which will be released for free in November. So, I guess that would be five old maps and seven actually new maps.

Call of Duty: Black Ops 4 is out on October 12. It includes the Blackout battle royale mode, competitive multiplayer, and three Zombie campaigns. The game starts at $60 (USD).
