Sentry Drone

What it sees, Lo Pan sees

Sentry Drones are a type of Decepticlone from the Transformers (PS2) video game.

Sentry Drones have very little combat ability, but they're not really meant for combat. They are deployed into the field, typically in mazelike areas with low visibility, to watch out for invading Autobots. Once they spot an intruder, they launch a flare high into the sky, signalling nearby Decepticlone units to come in and take care of the problem. As such, Sentry Drones are best taken out from afar.

Poke out the eye in the sky

Sentry Drones tend to run once they've released their signal flare. If cornered, they have a light laser blaster to keep their persuers occupied. They cannot fly at high altitudes, so their escpae options are fairly limited.
