Area 51

List of Features

* UFO Hunter-Killers
** Large Scouts, Terror Ships, Battleships and Overseers have a chance of being generated as a Hunter-Killer (HK) while performing Alien Retaliation, Terror, Infiltration and Base missions
** HKs will attack any XCom craft they detect
** HKs can also escort other HKs
** Alien bases can also deploy HKs to intercept incoming XCom craft, with the number and type of UFOs launched progressing over the months
** XCom Interceptors can now be assigned to escort transport craft like the SkyrangerBombers are used for Interdiction missiles, which can also destroy facilities by aerial bombardment
** Pressing 'T' while on the globe will display a list of detected UFOs
* Officers and Training Room - a soldier now needed to be trained to progress past Sergeant level; training room also allows for up to 10 soldiers' stats to be improved
* Redesigned Geoscape globe, with new textures, regions, cities and country zones
* Terror missions can now appear also as Escape variant, where your units need to reach the exit area before a timer expires otherwise they're MIA
* New monthly Council missions, can consist of 6 different objectives: Defense, Assault, Destroy, Capture, Recovery or Extraction
** Recovery, Extraction and Capture missions give research rewards into early game tech (Alloy, Gauss and Laser)
* In Terror and Council missions it is possible to encounter allied soldiers and police officers who will attack the aliens, but they carry only conventional weapons
* In Escape and certain Council missions, XCom will use the Mudranger APC for deployment/exit instead of the transport craft

Other Mods and OpenXCom's Options
Area 51 should be fully compatible with any mods that don't involve changes to the vanilla missions and research. Since I wanted to keep it as closer to the original as possible, it doesn't include any mods involving gameplay mechanics or UI changes, so that everyone can choose which ever of those they like.

Do NOT use this mod with any of the following mods:
* Terrain Pack (already included and expanded in Area 51)
* Final Mod Pack
* Piratez
* X-Com Files
* Hardmode Expansion
* Any other megamod

Regarding OpenXCom's options and official mods, here are my suggestions:
* Don't use XComUtil's Improved Ground Tanks, since there's already a tech called 'Improved HWPs' which is the XComUtil's improvement, allowing you to upgrade any existing HWP to Alloy HWPs
* Same is recommended to XComUtil's Improved Heavy Laser, since there's a Laser Sniper Rifle with the same stats
* Limit Craft Item Capabilities can be useful, because if you're use an equipment pile during battles, in the new Escape and Council missions all those items will be lost unless they're not in the exit area when you abort the mission, and usually they'll be spawned in the open because there's no way to control where the first soldier is generated since it's random. Using the original's 80 item limit per craft trains into always carrying everything on your soldiers due to the restriction
* Instant Grenades and Explosion Height 3 (just for fun)
