Grey

Greys are aliens held by the military at Area 66 and forced to compete in the Deathwatch game against their will.

Appearance
They are slightly short hairless aliens with melon shaped craniums, large black eyes, no noses. Overall, they are pretty typical depictions of Grey aliens, except for having slightly muscular builds.

Background
The Greys, for one reason or another, were either prisoners forced to work alongside secret military personnel to invent Martin, or collaborated to help invent Martin of their own free will, and when the current game of DeathWatch started, they managed to escape their holding cells.

Involvement
Greys are Grunt Enemies which appear in Road Rampage and the Money Shot II Bloodbath Challenges.

Greys will also escape during the DeathWatch Challenge in the Facility level, catching one will result in 99,999 point bonus.

Strategy
Greys are virtually harmless, the only trick to killing them is catching them. Usually the commentators will quote, "Man, those greys are harder to get than twin sisters when you're down to your last roofie" when one is near you.

Do note that the 2nd level has 3 Greys that are optional to kill as a Deathwatch Challenge, and they are armed with rather dangerous laser guns. However, one Chainsaw hit will kill them.

Note: The standard enemies of Area 66 will attack Greys on sight. If they kill any of the Greys before you do, you will fail the DeathWatch Challenge

There's also a Grey Boss named Martin; who is the 2nd Rank boss in DeathWatch.
