As much as I don't want to be the cynical twat that shits on your parade, personally, I thought that promo video was terrible as far as advertising your game goes. You didn't even come close to doing it justice.
Advertising costs a lot of money, but making promo videos costs mostly just time. If I were you, I would be making a longer one, that not only shows highlight reels of skill shots as interludes, but also breaks down each weapon, each vehicle, the powerups, the movement, the number and type of maps, even the skins that can be earned or the skill based ranking system etc.
This game has a lot of great things going for it, that promo video didn't even come close to showing them off. Your USP (Unique Selling Point) is nowhere to be seen in that video, other than it is an Arena FPS, and sadly for you guys, those are back in vogue with many reboots on the horizon.
You need a video that makes your game stand out, that actually gives people a glimpse of what they are missing if they don't buy it. If you don't manage to build a solid playerbase on day one that can last for the following six months to give you the time to iron out bugs, balance issues, and draw in more players, this game wont succeed and all of your hard work will be wasted.
None of us want that, and I honestly believe that making a solid promo video to not only generate hype, but to also educate people on what they spending their money on, is far better than a few flashy killstreaks. Please make a new one, and make your game stand out, not just because it deserves to, but because if you don't, there will be thousands of players in years to come that will find your game, and wish they had known about it and played it before it died.
After all your hard work, and the effort you have put in to give us everything we have asked for during beta, I know you can do a much better video than that. It was nice, don't get me wrong, but nice guys come last, you need to make it the alpha male of promo videos, so that anyone who watches it just has to play it.
