Defeating Grays
To defeat Grays that use shields, mutate and fire parasites at them. It will bring down the shields faster than any other weapon in the game.

Defeating the Super Beast
When fighting the Super Beast, rather than running straight at him, run around in a circle. When he gets near an explosive barrel, shoot it. It does more damage then the BBG. Watch out for his plasma shooting arm as well. When you finish, Edgar will talk to you, and you get to see him.

This will get you about 255 lives, 255 continues and 255
health points.

To play as an alien Kronn Hunter, you must shoot *only* the
first
three STAAR Team members you see on the Front Tarmac (Wave 1), as
you start the game. Don't shoot anything else!

You will be restored to your starting number of lives, and you
can
play the entire game (including secret rooms), and even get *two*
unique storylines at the end of the game (one mission failure,
the
other victory). The powerups and stat plates are all different,
too.

Kronn mode, if you can handle it, is the highest possible
scoring mode
in Area 51. At each update stage, you will receive an additional
20,000
point bonus. It will also put up a green alien symbol on the high
score
screen if you make it.

Location of Bonus Rooms in order of how they appear in the
game.
X MARKS THE SHOT:
To activate, shoot all the windows on the outside of Hanger
18.
Two windows can only be shot when the screen is scrolling to the
right, past the hanger.
TANK TOP:
When you enter Hanger 18 shoot as many of the windows above
you
to the right as you can. Later when you get on the fork lift, you

window left seen. When the screen scrolls back left, point at the
remaining windows and shoot them when the screen completes
scrolling.
HEAD QUARTERS:
Shoot the three blue lights when the first missile guy is
shooting at you. One is in the upper left corner; the other two
you shoot after you go around the capsized truck. They are on the
right side of the screen and you can only shoot them when the
screen is scrolling. You get another chance after the Stat's
screen when the screen scrolls to the right.
CHOW PALACE:
Just after you get the power up shoot all the windows along
the
far wall. Shoot all the windows as you walk along to the right.

While you are on the fork lift, shoot all the barrels (every
last
one of them).

cockpits' windshields on the F-15 planes. Shoot a total of 3.
Then the windshield on the big C-5 plane.
EGG CELLENT:
When you are in the first hallway in the ADMIT building. Shoot

the General's Office.

There

stationary barrels.

visible
explosives.

Here are some hints on getting into just a couple of the seven
secret rooms
hidden in Area 51. There are fourteen separate secret rooms
entries...
In the Hangar (Wave 2), shoot out the three blue
"emergency" lights during
the first lockdown. There is one to the left and two to the right
of the
red tractor truck. You have to get the one on the left during the
quick
camera pan. This will get you into a room where aliens are taking
a latrine
break. There are 36 items to shoot in this room; six of them are
aliens.
You can score over 40,000 points by hitting everything - a major
scoring
opportunity! This entrance to "Head Quarters" is secret
room entrance #3.

By shooting all 15 windows in the back of the hanger, players
can get into
the secret room entrance #4, "Chow Palace." This will
open up into a huge
power-up feast, with 21 icons: two give shotguns; two give
machine guns,
and 17 give grenades. This room is also the only place in the
game where
you can see a Stage 2 alien, the intermediate bioform between the
Stage 1
zombies and the full-blown Stage 3 Kronomorph alien. Here the
Stage 2 is
happily munching on a poor human.

When you get into the Admin Building (Wave 4), shoot out the
first "exit"
sign and the first three ceiling lights right around it. This
will get you
into a room where there are disturbingly cute alien babies hidden
insi de
eggs. You can score over 15,000 points in this room. This is
secret room
entrance #9.
