Attack Of The Infectrons

in Brain Training

X-03 is a desolate and dark planet.But there is precious plutonium ore here, so mines are paid well to work here. There is a catch, though, alien species known as "infectrons" also discovered that they like the ore... The plant`s auto defense system can handle only up to 50 infectrons on it`s own. Your task is to hold the infectrons back as long as possible so the miners can organize a defense at the plant.
