Holdout v5 is an Infection map a made a while back that goes with a Gears of War gametype I made. It uses all three levels of Sandbox, with the Zombies (Locust) spawning in the Crypt and the Humans (Gears) spawning in the middle. And in the SkyBox is three Hammers of Dawns, each with one Spartan Laser.

Here is a picture of the Hammer of Dawn in action. Each one only has one Laser that spawns once every 3 minutes, but in good hands it is a lethal weapon. But try not to camp up in the Hammers, because I know it sounds like a good idea, but you WILL die eventually. There are three Teleporters up to the Hammers, each leads to a different Hammer. They are all located inside the house.

This is the house the Gears spawn inside of. It has a Rocket Launcher and Shotgun in the spawn area, and a Sniper upstairs. Also in the spawn area are two Turrets, and a Mongoose. With good teamwork, the house is the best place to hold off the Locust. But a trip to the armory first would help too. And a Transport Hornet spawns outside the house after 150 Seconds.

That is the armory. It has a somewhat decent variety of weapons, so there's something for everyone. And in the background is the Alter, which has a Laser in the middle.

The Gears' Garage and Sniper Towers are shown here, both are only a short distance from the house. And yes, there is a Sniper Rifle on the Tower.
*NOTE: This is an older picture of the Sniper Tower, I more recently Ghost merged the ramp into the main tower.

And this is the Locust's spawn area. Better weapons spawn as the game goes on, such as Rockets and a Laser.
*NOTE: There is a Custom Power-Up in the Weapon Holder which makes you General RAAM for 90 seconds. And if you want the Turret, rip it off first.

And an Aerial view of the whole middle area.
