Guys Pls Tel me how to escape in the mission "343 guilt spark" in halo..

Before you follow 343 guilty spark pick up the shotgun if yov already got it then it's the best weapon to ues aganst the flood but a plasmer rifle is also good and try to keep as many granads as poss plasma grenades as you can then all you half to do is walk into the room that has no way out of it because all the doors are locked kill all the flood and a door will open go half way through it them go back into the room there will be more flood in there and then through the door that just opend some pregnant flood will come through walk into the locked dorr in front of you turn around and throw 2 plasma grenades and some of the mom flood will walk in front of the rest of them and use the shootgun and shoot the mum closest to you them crouch down it will bring your shealds down half way but there will be about 2 flood left kill them then go through the door and 343 will be there waiting fore you follow him and you will be in a room full of flood use all your grenades and them walk past and shoot as many as you can then you will go through a door and cortana will tell you your in the right place but 343 will not be happy about not lettin him use the rings to stop the flood from leavin the ring then you will have compleated the level.

Since the last user made a big paragraph of how to escape, i'll just give you two videos. They are walkthroughs with voice commentary. I take no credit for them because I found them on YouTube. I hope they help you out.
