Folks
Few ideas for new aliens mission. Possible to create even in vanilla. I made trajectories for every mission and almost complete maps / UFO for them.
1) Convoy shipment mission
This is a mission when UFO like freighter starts in area 5, goes to area 0 at low speed, then goes to 5 again. Crew is medium size, weapons are small, but there are additional elerium / weapons inside ship. This would be nice to shoot down this UFO for its prize. This is like supply ship just without alien base.
2) Transfer prisoners mission
Just like mission 1) but instead of items / elerium there will be additional civilians on the battlescape. This would be similar to terror mission but in this case aliens have just limited crew and X-com can score points by saving a lot of civilians / prisoners. There could be even special type of civilian for a score of 500 and game would change into Kill or Save the King.
3) Officers holiday mission
Same as above but instead of civilians or a supplies the prize for player would be sleeping / stunned live alien commanders or officers taken life inside cabins of almost civilian alien ship.
4) Prison camp mission
This is something different then above. Alien UFO starts at 5) and lands anywhere on land for a long period of time and then goes again to zone 5). It is quite simple to shot down UFO but if lands then crash site turns into nightmare. Instead of normal UFO there are gray / blue citadel UFO like a camp with civilian people inside it. Someone made a UFO from those blue Cydonia piramids already. Rest is like terror mission. Score for mission is like 250 and its scored after UFO takes off after long time so its best to approach it when land.
5) Commanders meeting mission
This is similar to 4) but instead of very weak UFO that is easy to shot down this time UFO is very difficult to shot down. The major difference is that UFO contains 4-5 Power Source and all aliens are near those power source. This means UFO is very dangerous when touch down but very easy when shutdown by interceptor because most of aliens would be killed by Power source explosion. Total number of aliens inside this large flat UFO (30x30, one level, no walls inside, just open space inside that would simulate flying alien HQ) would be larger then battleship, and mostly it would be high ranked aliens. One of the aliens would be main commander or admiral or just several commanders that would allow for higher score / getting more equipment.
6) Annihilation mission
Large UFO starts at 5) goes directly to random city at zone 3) lands there scores 50 points, move to next city at low speed, move to next city at low speed, move to next city at low speed, leave to zone 5). This would simulate final assault of aliens on cities and instead of single terror mission it would generate large number of points every time UFO takes off. This is something taken from Apocalypse so UFO like mother-ship would be required.
7) Raid mission
Is same as 6) but instead of zone 3) UFO will land on area 1, 2, or 4) No patrolling, just land 3-5 times for a short period and move further.
Interception mission
Aliens cannot track x-com crafts but we can simulate it. Just move UFO from zone 5) to zone 0) 3-5 times at max speed and altitude and then leave to 5) This would simulate interception mission and special type of alien UFO would be needed = smaller crew, better weapons.
9) Surprise attack mission
I wonder can we made a mission where aliens actually have no weapons in their alien deployment setting but instead UFO contains a lot of ammo / weapons inside it. So aliens must pick weapons first before actual battle begins. No alien outside UFO. Time is the essence so for x-com is required to act ASAP to kill aliens before they can pick weapons.
