Ace Combat 8 Moon 11 — Selene (Carmille Tewy)
Moon 11 is Major General Carmille Tewy, callsign Selene — commander of elite Sotoan squadron Lux Lunae. In Mission 29 she flies the X-40 Nightmare and tries to laser-guide a Tonitrus Spear onto a nuclear Land Battleship near Theve. Surviving turns is not enough — you must break her guidance.

Mission 29 fight priorities
- Pressure the X-40 until guidance on the Land Battleship stops — hanging back to “tank” the clock fails the op.
- Don’t dump your entire SP magazine on early adds before her hard phase.
- Optional ace Prudens (Su-57): fly under an urban highway bridge on Veteran+, then finish. Automatic Selene / X-40 Assault Record is separate.
- Playable X-40 unlock is Tree progression after campaign — not the same as beating her. See X-40 unlock.
