We havent had a real trailer that builds hype since E3. I want something like this

Campaign that shows gameplay along with epic music. I really hope we get something like this at E3 not some Vidoc

Yeah. Most likely 343 will show some during this years E3. Check out the vid above hyped me up a bit even though it’s fan made.
They probably will nearer its release. It takes time and people away from development and testing, which they say they are doing a lot of. Hopefully they’ll give us a trailer, probably consisting of multiplayer games and some campaign. I can’t imagine they’d do a lot of it because they want to keep it a surprise.
Hopefully it will show off the game as a whole, not just the best bits or individual components such as campaign only or multiplayer only, unless there are specific trailers for each.
There may be a trailer at E3.
I would much prefer a good look at the multiplayer. Either a nice vidoc or long trailer showing a good example of what we can expect. I don’t expect to see anything substantial until marketing gets up to that point.
I would prefer them to show very little of the campaign. Say like the first level against the Cov, and maybe level designs and environments of Reqiuem. Leaving all the rest a nice secret until we get there.
I want a trailer that shows off some of the games ability whilst not giving away any campaign secrets or anything like that, i dont wanna see the new enemy until i land on Requiem, walk through some forerunner city, all misty and then see a shadowy figure appear from the mist and start shooting, and after a long battle kill him and go up to his body, and finally see what im up against.
Sorry i got sidetracked lol.
It be pretty cool if they did what Bungie did with Halo 2. The developers could play a FFA game showing us how multiplayer works.
