[b]Extreme orbit of Planet N-1[/b]
Three Varren WarCruisers abruptly appeared in extreme orbit, about as close as they could get to the planet without the gravitational orbit pulling the ships apart. One moved to a deeper orbit, to begin using orbital bombardment on both the infected city, and the infected jungle and desert. The other two ships accelerated towards the three waiting Explorer ships, with enough radio chatter going between the five ships to charge a battery. As the five ships convened in tactics, enemy tactic data, and battle plans, the first Varren began firing barrages down onto N-1, after firing probes to detect the edges of the infected area. 

Once they pinpointed the rough area where the infection was, the began to fire in circles around the sector, isolating it with a rain of fire. Shortly after the area had been isolated, including the city, nuclear warheads were launched. Two, actually. Both were sent on high-efficiency courses, and when they struck soil, the two warheads detonated with a massive explosion, the two warheads combining at their meeting point to create a lengthy, oddly-shaped mushroom cloud, cleansing the soil of both nutrients and of otherworldly parasites and worms. Afterwards, continued railgun bombardment continued to hit any spots that appeared to have foreign particles, or had caves, tunnels, or any other possible shelter from the nuclear blast. If nuclear weapons proved ineffective, then antimatter and plasma research would have to be taken to a new level.
