README for Version 0.99.9
# This Mod is aimed at experienced X-Com Players #
# Who like a challenge :) #

About this mod:
This mod intends to make the gameplay more challenging and deals with
most of vanilla versions flaws, like overpowered Psi and early Plasma ownage.
It sticks strongly towards the vanilla core components and builts upon them.
It is aimed at experienced X-Com players, who know the game well and are
not afraid of a difficulty higher then Superhuman. The Aliens have more
variants and your weapons will slowly become obsolete due to them.
Research progress is a must, but comes at costs.

For playing you should choose difficulty Superhuman, since the mod is balanced
to be played on Superhuman difficulty, otherwise you wouldn't have the full experience.
The difficulty will be actually far higher then Superhuman, considering mainly the changes in economy and research.
Technologies will need alive aliens captures to unlock and will trigger additional mission.
Research takes longer and you do not have access to a alien
containment from the beginning. It is recommend to get between 200-250
scientists by November. Otherwise the game becomes extremly difficult.

The vanilla game always lacked proper weaponry sets including melee weapons, shotguns, sniper rifles. All of these have been added for the ballistic and laser weaponry for X-Com and the Alien plasma weapons.
A extended set of additional grenades and small launcher ammo together with added grenade launcher gives very good indirect fire possibilities. Small launcher acts as a artillery style weapon, arking shot ;).

More armors, starting with ballistic vests up to reinforced power and flying suits expand the survival capabilities of your soldiers. Power armor also extends stamina and increases carry capacity.

Have fun exploring the new drones and tanks, which will draw alien fire and help detecting targets to shot or support your wounded troops. Drones may even help with capturing alive aliens.

A large number of terrains from Hobbes terrain pack and other mods (65+ additonal terrains) have been integrated and partially overworked (bugfixes mostly).
A extended set of maps has been added, featering turned version and additonal maps modules to make fighting within alien bases more enjoyable and tactical challenging.
Aliens have a couple of more UFO types, Fighter, Sentry, Excavator and LabShip.
Vanilla UFOs and new UFOs types all have extended set of interior maps variants (total 124 map). So enjoy exploring these.

Aircombat has been balanced, UFO's especially big ones will shot your interceptors.
A faster and much more durable interception craft has been added, also a enhanced skyranger version, with a back door.
Swarming Terrorships with interception craft is highly recommended.
The Laser cannon is actually useable now ;)

Being able to interrogate alive aliens requires you to raid a nearby Alien Base early.
Otherwise you have no tech progress. The base is located in your starting
region. For the time being also one of the Story Items is located in
the alien base. Raid this base as early as possible!
The game can only be won by capturing and interrogating a Ethereal Commander who unlocks the final mission.

However your run goes, let me know your feedback and how i can enhance the mod further.
For a detailed list of changes (may contain spoilers) see the Features further down.

For a real challenge play the game in Iron Man Mode!
Please do no use the OpenXcom Iron Man option and enforce your own Iron Man Mode, its a big mod, so bugs may happen.

I hope you will enjoy this collection of 60+ Mods (i stopped counting)
and please report any possible Bug you might find on the forum.
Feedback of any form is also appreciated.

Any chance of doing something similar with TFTD?

Mutantlord @mutantlord

Monduras @mond1608588080

could you release the craft as stand alone mods?

hellrazor @hellrazor

The exist also as standalone mods. You just have to search through the modportal.

Monduras @mond1608588080

sheesh you weren't kidding on hard mode... first month base defense with 30 floaters and reapers and cilicoids... only survived with 2 tanks and a drone lol... any updates?

hellrazor @hellrazor

You can download the Version 0.99.8 from my github account. But i had to remove the globa terrains from the Terrain pack, i guess i am going to integrate the globe maps from the Community map Pack.
