the level is arbiter. i am going to make a video on how to get all of the skulls. my username is brendanspartan142
This skull is a silver skull. It is strictly for your entertainment and you won't get an achievement for it.
You do not have to find the skulls in any recent version of Halo. If you mean Halo 2, then I'd recommend reloading the level.
it pretty much makes the aliens mad and they try harder to kill you. like the grunt that tries to kill you whe you get the skull.
Its not an achievement, its a silver skull. On the mission "Crows Nest" (the part where the bugs are coming from the pipes after you drop down and Cortona talks to you, at the end at the edge), you will notice that you can go underneath the walkway you were just on. The skull is at the back of that passage.
Skulls modify certain aspects of the campaign, often increasing difficulty. For instance, the Blind skull completely eliminates your HUD and the Mythic skull increases your enemies' health. Some are amusing, such as Grunt Birthday Party, which causes confetti to launch into the air from a Grunt that receives a headshot.
There are no cheats, however there are the good old fashioned skulls which make the game more entertaining, such as, Grunt Birthday Party and IWHBYD skull, although they give you no real advantage they are very entertaining
They do the same thing they did in Halo 3. You can "activate" any of them during campaign for different effects. For example, the "Grunt Birthday Party" skull makes an extra sound effect and confetti whenever you kill an enemy with a head-shot. Unlike halo 3, you do not have to find them this time around.
it ether affects the gme to make it harder or it makes more fun like the grunt birtday party skull when you shoot a grunt in the head but all but two of the skulls make it harder so if you search this then you must like halo i would be suprised i you dont it is a great game if you want to know more then just ask me ok i know most there is to know about halo.
No halo reach does not have cheat codes. But, you can do glitches and turn on skulls, such as the ONI: Sword base credit glitch or the grunt birthday party skull, and even the Grunt dance party.
a grunt.
No but you can be a grunt in halo1
