*BAM!*
The bunch of younger worm-like creatures was breaching out of the tunnel's exit just like how the zombies did back at the entrance they dug.
"Fire all the Decimators at the tunnel, now!" Satella gives out the order without hesitation. In this situation, the tunnel's integrity is no longer their concern as long they can protect themselves.
Warheads were fired at the tunnel where the creatures were pouring out. An explosion followed after an explosion, along with blood and flesh splattered everywhere. It continued for quite a while until there's no longer any sound coming from the collapsed tunnel.
With the tunnel now collapsed, the group now has no other choice but to continue forward. Their only option to return to the Wind Base is through another entrance, about 20 miles away or through the woods.
