"War is the worst possible way of gathering knowledge about foreign civilizations."

Stanislaw Lem


What is XNT - Into Darkness?

This mod is a compilation of hard work done by multiple users, players and the Xenonauts community. It implements innovative elements and mechanics thus altering the players experience.

What makes it different?

XNT - Into Darkness is designed for players looking for a faster pace of play and more action, it mixes in specific mechanisms and modifications that make for an exciting and diverse environment. The second important difference is decision making: the player has to choose wisely weather he prefers to focus on economy, air supremacy or rushing additional ground combat tools. The idea is to provide the player with more choices from the very beginning, so that the player can take his own unique path towards victory...or destruction. Be aware: XNT raises the difficulty level.

How to start?

First you must understand that there are various forms and parameters that allow you to start the way you want, however there are several alternatives or pattern to start playing:

- Air Supremacy, focus your initial resources to build up a powerful and destructive fleet of aircrafts.

- Economy Factor, prepare multiple factories and sell your mass-produced equipment. (Beware based attacks are frequent).

- Armor Rush, if you want to ensure your supremacy and survival of soldiers in combat, you need to focus on developing heavy armed vehicle platforms (tanks).

- For Science!, designate several research divisions ready to diagnose and take advantage of the new and powerful alien devices. You will always have cutting edge technology in combat. If you can still afford to produce it.

- Imagine your own way, there are thousands of ways to address the issues you will encounter.

You touch me in all the right places, and have left an impression on me. Much like my cat pushing it's body against my leg trying to get my attention whilst i am trying to play this game. Nevertheless i am impressed by most of the content, dual guns? Yes please. A nice blend of several mods together that i love with a little sprinkle of chicken salt? yummy. Sadly whenever i review something it ends with me talking about food. Pizza.
