The Great War of the Worlds



The Great War of the Worlds

An alternate history Total Conversion by efrenespartano, alinare & Luke83

Set in an alternate timeline where the Martians of the H.G. Wells masterpiece really invaded Earth in 1896.
Swept by bacteria, the invasion came to an end just a couple of weeks after it started.
Humanity united and rebuilt and prepared for the worst. 12 years later, the mankind's worst nightmares came true. In 1908 the Martians launched a second invasion, this time more deadly.
Since they crash landed in Tungunska, their progress has been almost unstoppable.
From the Siberian tundra to the African jungle and the American Midwest, half of the world belongs to the Sons of Ares
What remains of the humanity united under the banner of the Coalition of Nations and have gone on the offensive.
Your unit is one of elite, formed with the best that the armies of the world have, the International Expeditionary Force.
The year is 1914.
This is the War to End All Wars.

Known issues:

*This is an open alpha, only the Tier I & II human weapons, Martian and their guns, plus two Tripods and three UFOs are available.
*The weapons are very unbalanced
*The Triffids may crash
*The custom damage types are not in the Martian armors yet
*Custom research still not available yet
*Some tiles in the Trench map are buggy
*The Medikit UI is not complete, to exit the interface, you need to tap below the last number
*Issue with Commonwealth Field/Gas Mask uniform, missing info & buttons (found by BlackStaff)
*Various UFOPedia pages about Line Infantry (Mechtoids) are crashing (found by BlackStaff)
*Advaced Firearms and Improved Metalurgic Techniques pages are crashing (found by BlackStaff)
*Could be hidden bugs and crashes. Don't forget to report them!

*Try the weapons as much as you can, we want to balance them and your feedback will be fundamental to do it. At the moment, we have not included all the features and we have maintained research, races and vanilla weapons. In theory it should serve along with any other mod. As soon as we launch the complete version, we will deactivate most of the vanilla stuff
