“Bear’s Den” is my twist of the old “Rat’sNest” on Halo 3. It’s basically the same concept, a giant road circling themap. It started off just a simple twist to "Rat's Nest", but it ended up being much more complex. The difference is, this is meant for big team; there are two levels: theroof of the complex is accessible through ramps and gravity lifts. The map iscompletely symmetrical, except for crates, barricades, etc.
Two ghosts spawn on the topfloor, but any vehicle on the lower level can make it to the top, creating someinteresting situations. It’s up to you and your team where to keep the vehiclesupport. But to keep the heat of the battle on the lower level, not much coveris on the top. So yes, I did that on purpose.
The light bridge on the top isthe highest point, which contains a rail gun, and directly below it is theintersection of the 2 middle pathways (which has a gravity hammer). Next to thebridge are two man cannons, making traveling faster, considering how huge thismap is. All four machine gun turrets are placed on the top level, all in verystrategic locations.
The map works best with morepeople. Four team slayer is very fun as well. Playing with two teams, theyspawn on opposite sides (obviously) but can see down the narrow hallway to theother team. If you walk forward a few steps, there is a sniper available forboth sides. On the left and right tunnels are sticky detonators, and the restof the weapons you will find by playing the map, but are listed below:

2 Frag Grenades (2) [90 seconds]
2 Plasma Grenades (3) [60 seconds]
2 Pulse Grenades (2) [30 seconds]
Gravity Hammer (1) [150 seconds]
Sniper Rifle (2) [120 seconds]
Needler (2) [120 seconds]
DMR (2) [60 seconds]
BR (2) [60 seconds]
Plasma Pistol (2) [60 seconds]
Sticky Detonator (2) [90 seconds]

Ghost (4) [120 seconds]
Warthog (2) [120 seconds]
Mongoose (2) [90 seconds]

Reminder: This is only the top view; there are many more sections to explore.

When you spawn on team based gametypes, this is what you will see.

The two tunnels on the side are identical except for scenery; the side hall entrance is to the right.

Looking into the center of the lower level through the side hallway.

Directly above the lower level intersection is the "light bridge", with the two man cannons and railgun as said in the description.

View from directly above the lower level spawn, angled down to see a better view of the room where the sniper spawns at.

A view looking into the spawn zone is above.

Again, not much cover up top. To the left is the side tunnel, and the right is the spawn of one of the two teams. The man cannons shoot you to the ghosts on the top floor (you can picture that better by seeing this screenshot).

Enjoy! Comments and critisism please. :)
