What's new:
-. Called a new resource, "Meld", which can be collected on the battlefields and called with the help of gene modifications or implants can be added to the soldiers (brain, eye, breast, skin, legs, ...)
- Gene modifications: the soldiers have the opportunity superhuman (according to research appropriate technologies) implants to how to get unique armor and weapons, in addition to existing of up to 8 different designs badges can be decorated
- Use a new class called soldiers "MEC" (mechanized exoskeleton cybersuit) with its own skill tree, a no longer quite human cyborg, the exclusive armor and weapon parts, but can not have PSI capabilities
- New weapons, led by the MEC for the class, for example, Minigun, railgun or particle gun with a lot of "bang", which can be individually equipped with badges, such as the "Tiger Shrimp" ;-)
- 2 new basic structures: the Genetics and Cybernetiklabor
- 2 new alien species: the "Mechtoid", a Sektoid in Mech armor and plasma Mini-Gun and the "finder", a flying, octopus-like robot unit that can camouflage itself
- A new enemy or when fighting faction, the "EXALT" (a secret paramilitary human society that sympathizes with the aliens)
- A new submenu in the operating room to combat EXALT: the "covert operations" means any successful mission brings new clues to the hidden base of EXALT that can destroy attack mission in a special (base)
- 8 new human enemy types of EXALT fraction (4 standard soldiers and 4 upgraded, genetically engineered elite units)
- Many new technologies, including for example "deep pockets", which the soldier an additional charge of each weapon gets (rocket launchers, grenades, etc.)
- New weapons, including 4 new grenade types like gas or "flash bang" grenade
Finally give new research projects, for example, all classes 2 Item Slots - (!)
- 5 new "second wave" Options: aiming angles (soldiers receive a target bonus for flanking enemies), save scum (a saved game is the connection of an action does not lead to the same result), itchy trigger tentacle (not Overlap Aliens ( Mechtoids, Cyber discs Sectopods) have a 50% chance of getting soldiers to shoot as soon as they are discovered, training roulette (each skill tree a soldier randomly composed), at least vs Mattersburg (PSI soldiers can not be genetically modified, and vice versa)
- 47 new cards (battlefields) and partially revised and optimized map the main game
- New game features such as getting medals for the fulfillment of special mission objectives that can be awarded to the soldiers and one of 2 selectable upgrades allow (eg no panic attacks, +5 goal accuracy at enemies in cover, ...)
- New mission types: Covert Operations (Covert Data Recovery, covert extraction) operation Progeny (originally planned as DLC, consisting of 3 missions and can be separately activated from the Start menu / deactivated with it very X-Files like a woman named Annette with mystical abilities is that possibly may accede to the XCOM team even - exciting), site recon (Mission in the docks of a Canadian city including Zombie plague) and finally "Operation Ashes and Temples":.!
BASE DEFENSE !!!!!! Yeah! -> The player controls randomly selected soldiers from its barracks with the respectively equipped at the time equipment and some units XCOM security personnel on a large, special card. You have several waves of aliens attacks exist and also receives random supply of security personnel in the course of the mission. The failure of the mission leads to the end of the game!
Such is an addon and all XCOM fans will take pleasure with the unique new features. By now really greatly expanded variety and the players will surely addressed, where the main game than the original was too "slimmed down" something!
The only shortcoming: there are no new campaign - the additional content is seamlessly integrated into the campaign the main game!
UPDATE 25/11/13 v.:
Now that I have spent several hours with the addon (in Ironman mode!), I can say that the feeling was now very well captured from the original. Especially the new mission diversity with EXALT threat to many other Möglichekiten in the game and especially the varied new cards incl. Special events (Zombie Mission!) Leave the game for me mittlweile appear outstanding. I recommend all of the functions of the "second wave) to activate and the Ironman mode. Then you have neat strategy and tactics lining and every decision counts! Class, so a strategy title should look like!
This year again for me the (strategy) game of the year!
