On April 19th, 1973, a race of extra-terrestrial lifeforms launched a landing unit from the moon, which touched down on Earth, in central Asia. Ever since, mankind has been engaged in a losing war against this alien species, known as the BETA, as they have gradually expanded outwards across the globe.

If Niigata falls and the mountains in 
Gunma and Nagano become BETA territory...
...إن سقطت نيغاتا وأصبحت الجبال في غونما وناغانو منطقة للبيتا

las montañas de Gunma y Nagano,
Si Niigata cayera y los BETA tomaran
las montañas de Gunma y Nagano,
Si les BETA prennent Niigata,
Se Niigata dovesse cadere e le montagne 
fra Gunma e Nagano diventassero territorio dei BETA
Se Niigata cair e as montanhas de Gunma
e Nagano se tornarem território BETA...
Если Ниигата падёт, а Гумма и горы 
Нагано будут во власти БЕТА,
