Gantz 312

At the end of the previous chapter lots of gantz players appeared and quickly overpower the aliens. They tried to take them as prisoners. The aliens try talking but, couldn't be understood. Then, they suddenly start attacking using their wrist-weapons. The gantzers weren’t expecting them to attack because they were unarmed, many died before they kill them all.
Meanwhile T-Kurono was leading the school. The streets were full of corpses. The gantzers came from all over the country to fight the aliens. Night comes and the invaders retreat temporarily.
