I think the game build some new string from the mission/deployment string, which is STR_ALIEN_GATE / STR_ALIEN_GATE_ASSAULT. But I don't know what it is so I can't give it proper text.
I've tried:
STR_ALIEN_GATE: Stand Pattern
STR_ALIEN_GATE_ASSAULT: ALIEN GATE ASSAULT
STR_ALIEN_GATE_ASSAULT_BRIEFING: Destroy bla bla bla
STR_ALIEN_GATE_ASSAULT_MISSION: Alien Gate A Mission
STR_ALIEN_GATE_ASSAULT_SITE: Alien Gate A Site
STR_ALIEN_GATE_ASSAULT_BASE: Alien Gate A Base
STR_ALIEN_GATE_BASE: Alien Gate Base
STR_ALIEN_GATE_LANDING: ALIEN GATE LANDING
STR_ALIEN_GATE_LANDING_BRIEFING: bla bla bla
STR_ALIEN_GATE_MISSION: ALIEN GATE MISSION
STR_ALIEN_GATE_SITE: Alien Gate Site
what is it?
thanks
