XXP is intended for players who want a vanilla like experience but with some new additions and changes, expanding upon Xenonauts without straying too far from the original. XXP adds 3 new alien types, 10 new weapons, 4 new aircrafts, 4 new UFOs and 1 new building upgrade. All new additions have been made with the intention of each having its own purpose and they all come with Xenopedia artwork and writing imitating the tone and quality of the original entries.
The gameplay has been rebalanced/changed in many different areas as well ranging from:
Geoscape balance when it comes to the air war vs the ground war | The ground war should be bit more relevant for making money and boosting relations. UFO landing frequency and duration has been drastically increased so you have the option to initiate GC missions without the need for air combat. Crashed UFOs have also been modified so that alien technology and the crew receive damage in the crash, resulting in less alien tech to capture.
Each vehicle has been given its own unique abilities | Vehicles now have positive and negative aspects to diffrentiate them more. Hunter - Scout and utility vehicle equipped with various rockets and a secondary machinegun. Scimitar - Infantry support tank equipped with a laser/plasma/MAG cannon and a secondary scatter laser. Also has the ability to drive through buildings and various objects. Hyperion - Artilery vehicle equipped with a laser/plasma/MAG cannon and a secondary cluster rocket system. Also has the ability to drive over water. To use the new secondary weapons you press the L key by default. The old laser/plasma/MAG cannons have also been altered somewhat to diffrentiate more as well.
More rocket types have been added | Smoke rockets and more vehicle rockets as well.
Stun gas has been changed to damage on contact | No more getting damaged once and then being invulnerable for the rest of the turn.
Dropship range and capacity has been altered | Charlie range decreased and Valkyrie range increased. All dropship have a 2+ capacity increase and the Valkyrie can now carry 2 vehicles.
AI Changes | Caesans are now more tactical and sneaky, make use of cover and stick together more. Sebillians are now more afraid of fire. Androns will "camp" less, be more aggressive and can crush through walls. Harridans will no longer fly around aimlessly towards the heavens like heathens only to get picked off by snipers.
Armour and HP rebalance for aliens | Armoured aliens other than Androns and Drones now actually use armour values, adjusted the HP for various units as well.
Weapons rebalance | Weapons adjusted for the armour and HP changes. Plasma and MAGs have been changed so that Plasma does more base damage while MAGs have much better armour penetration (mitigation), making them more effective against highly armoured units.
Xenonauts Armour changes | Buzzard made into a recon/sniper suit capable of nightvision and has an accuracy boost, at the cost of smaller viewing arc and thus now requires the live capture of any Harridan unit and can no longer be unlocked by defating drones. Small nightvision boost was added to the Sentinel and Predator armours as well. The Sentinel armour has also been changed to incorporate a counterpsionic system and thus now also requires the live capture of all Caesan psionic units to unlock for research. Lastly, the Predator has received a small armour boost from 70 to 75.
Alien crew changes | Harridans and Wraiths have been made into main races instead of being support races for the previous 3 main races (Caesans, Sebillians and Androns). Every main race except the Praetors have been given their unique support race. Praetors now only appear in Battleship and Dreadnought UFOs, and now receive a crew that is mixture of all the other alien main/support races.
UFO changes | All UFO types gradually appear instead of completly replacing previous UFO types. UFOs on research missions will land more often and terror missions/base attacks have been increased in frequency as well. Scout missions now slightly increase the main alien ticker size for every minute they are active on the Geoscape. Different missions have specialized crews, for example construction and supply missions have more non-combatants and low level units, while base attacks and terror missions feature more high level units and support races.
Alien Base changes | Now grow independently in size rather than being given a fixed sized as the invasion escalates. Discovery changed from automatic discovery to 95% approximate location and 5% automatic discovery every 3 days. Alien Bases no longer damage funding and instead increases the amount of max UFOs by 2. Alien Bases now feature mixed main race units with drone support and more non-combatants. Praetors no longer spawn in alien bases.
Alien Weapons are now captureable | No longer auto sold but their accuracy penalty has been increased from 50% to 75%.
And many other misc changes and additions | Funding damage/bonus adjustments. Starting soldier stats changed from minimum 35 to 40. Retakeable Xenonaut Bases activated (72h time limit). Dropship RNG survival rate increased when crashing over land. Armour changed to reduce suppression by percentage. Sell captured aliens on the black market. And more...!

This mod is not compatible with X-Division or other overhaul mods, Kabill's Tactical Armories or other ground combat and weapon rebalance mods, Armored Assault or other vehicle rebalance mods, Skitso's Sounds of Pain or any other mods that edit human death/injury sounds and any mods that add new armours. UI/script mods that edit _basebuilt.lua, sequipview.lua, combatguiexport.lua and combatguiexport_large.lua must be merged manually or their changes won't apply. Mods that change the art style of the soldier faces must overwrite or disable the new female afri05/06 and asi05/06/07 faces, or you will get vanilla art style faces mixed with the replacements. You must also disable the new Sentinel armour graphics or add faces to it, or you will get headless soldiers when wearing the Sentinel armour in the equip menu. Custom weapons should be compatible (as long as they don't edit the research requirements of existing entries) but balance with XXP can't be guaranteed.
XXP also includes variations of some mods that have been edited and merged into XXP. Do not use the following mods with XXP:
Better Armour Graphics
Unique Teleport Sound
More Civilians and Local Forces
Furies, Terror, and Dreadnoughts Oh My
