The Chronos is a Tier 6 ship in the Alien Intrusion mod. It fires a high damage frontal pulse with two medium-damage auxiliary lasers.
It's a good ship to one-shot most aliens and kill some slow t6 or t7 with the giant pulse. If you came across some fast ships, the auxiliary lasers will also do high damage to them. It's the few of the ships that can kill the yellow saucer alien 1v1 by overwhelming it with pulses before dying.
