Me playing the last level of Deimos Rising (using the level selection screen), with no deaths, and a shield bonus.
In the mines area, the game always spawns seven pairs of mines. I intentionally stall the killing of the final mine to allow the final set of panels to leave the bottom of the screen. This makes the next area easier.
In the final area, I use green shots to count how many waves of planes come down after the map stops scrolling. I attack the final ground target only after the fourth, final wave has come down, so no planes interfere while I am attacking the ground target.
