After evading enemy fire and enemy ships, the ship is caught by a gigantic laser fire that came from off-screen and is immediately destroyed along with every other ship in the vicinity.
The camera pans out to show a giant ship decimating the battlefield. This scene lasts for at least 10-15s.
[ INSERT GAME TITLE HERE ]
The camera then pans again and this time it will pan towards the front of the ship that fired the ray meanwhile the ship charges to fire another devastating ray.
The ray fires and decimates a whole swath of enemies again. The camera then pans slightly downwards to show only the battlefield and not the gigantic ship to show the aftermath of the death rays.
Then only showing the on-going battle in the sector, the title of the game would show up. And after a few seconds(3-5s), the gigantic ship is seen again, slowly moving in to join the fray. And then the teaser ends.
