Introduction
In the alternate timeline certain major events played out differently and Humanity made faster progress in Space exploration which resulted in major superpowers building space crafts and Lunar bases during the Cold war. In 1958 the Viking-1 rover succesfully land on Mars and captured several unkown creatures which resulted in the first contact between Humanity and the first extraterrestial organisms sparking interest on Earth before contact with the probe was lost. All other probes later sent to Mars were lost and no contact was made. Speculation on the mysterious aliens continued until 1967 when they arrived on the Moon. All attempts to contact them ended in failure and the Aliens quickly attacked Humans and Lunar bases which resulted in them being given the name 'BETA' initiating the first Lunar war.

The UN took charge of US and Soviet resources and modified various vehicles with guns and cannons with limited success. Mass drivers on Earth were also used to bombard BETA held areas but was soon stopped as the debris created issues and BETA continued to defeat Humans. Deployement of combat exoskeletons allowed humans to bring more firepower but only delayed the inevitable.

In 1973 a BETA Landing Unit arrived on Earth landing in Kashgar unleashing hordes of BETA and begins construction of the first hive on Earth. People's Republic of China refused foreign aid to monopolize on Alien resources and technology and launched a operation with ground and air units to defeat the BETA. Superior firepower and aerial attacks against the newly arrived BETA gave China the upper hand until BETA deployed the Laser-class which easily wiped out the attacking air units and made artillery ineffective putting the Chinese on the defencive forcing the PRC to request soviet aid. Joint Sino-Soviet "Operation Hongqi" to capture the still phase 1 hive ended in failure and attempts to exterminate the BETA hive with nuclear weapons also failed. Both Soviet and PRC forces began to retreat and used nuclear weapons for scorched earth tactics to delay the BETA advance. In 1974 the second Landing unit arrived in Athabasca ,Canada. However the USA after observing the disaster in Asia quickly took approval from canada launched a massive nuclear attacked which destroyed the landing force alongside turning a large area of Canada to an uninhabitable wasteland.
