Five stages of holding the line; this one lets you attack. An enemy eagle sits at the top behind steel, and a player shell that reaches it ends the stage at once for 1000 - enemy shells cannot touch it, so the stage cannot clear itself. Reaching it needs the mirrors. A shell entering one turns 90 degrees, capped at five turns and stepped one cell past the mirror so it cannot re-enter the same one. The eagle's only opening is a bullet-only shaft at column 8, walled in steel and fed by a "/" mirror below it, so only a shot travelling right along row 6 banks up into it; shooting left or from underneath deflects away. Mirrors block tanks and cannot be broken, and they block the enemies' line of sight so they do not waste shots. The clear/win paths were one block inside afterKill; they are now clearStage(bonus, note) so the snipe and the last kill share them. Checked headlessly: the snipe lands and pays 1000, the shaft saw 0 tank samples against 639 bullet samples, 6 idle runs left the enemy eagle standing, and closing r11's centre brought the base through 6 of 10 idle runs.
