the propane tanks can be found in a lot of places. if you shoot the caps off. it should start flying every where. becareful they can hurt.

the ghost on lockout is fake. it is just a computer rized spartan. they say that a guy goes to eat then the ghost showes up but really he is just another character. it's fake by how the guy reacts to him. the main guy just waits for the so called ghost to kill him.

the hole in lockout is fun and easy. go to where the glass in the celing is and you can go to the worp pad or to the bigger tower. crouch walk up in the wall by the door down to the worp pad. go to the left of the light. move right slowly till you get to the third black line in the light. while doing this keep jumping and it might take a few trys but eventually you will get it. you will know if you have done it by when you fall throuh the wall and land on the other side. yes the gardians can still kill you while you do this.

go to the middle of acension with the banshee. flip the banshee on the path way between the banshee pad and the center of the map. flip the banshee like your doing the banshee jump.( you will ned overshields and rockets) now do the banshee jump and if you did it right you should fly past the banshee pad and fall to the bottom of the map. now you can walk around. this might take a couple trys but it's fun in the end.

I've read in several previews that the range of the radar around a Spartan in multiplayer has been reduced. I don't have any good way of quantifying that, but it certainly seems to be true to me.

In particular, on Valhalla there are two rock outcroppings on either side of the stream where players often like to perch with ranged weapons like a turret, sniper, or laser. Often there's a lot of activity far away that they are paying attention to, and more than a few times I've run right up to such a player from behind and assassinated them if there's no one covering their back. It's also happened to me quite a few times as well.

I have a feeling that the radar may have lost most of its usefulness in many situations if this is the case. It can tell you if an enemy is nearby but on a different level, but doesn't indicate whether it is higher or lower, so this is of little use. Out in the open, you'll see a player long before he or she ever shows up on radar, so it's only good for detecting someone outside of your line of sight. If the range is so short, however, that it's routinely possible to run (not sneak) up to players and melee them before they have a chance to register an enemy on the radar, it makes me wonder if it shouldn't be either removed entirely, given a greater range, or provide additional information, such as the elevation of a target.
