It would all represent a certain industry of Sera, from transportation to beautiful government buildings, it would be the definition of Destroyed Beauty.
DLC: Wonders of Sera Map Pack
Cost: 1200 Microsoft Points
Contents- 10 Maps, 6 Character Skins, 7 Weapon Skins
Avalanche- A mountain range outside of Landown, after Tremors from Locust Tunnels nearby, an avalanche has been on the verge of coming true. This Classic Map returns, with everything the way it used to be.
Canals- Canals is an artificial waterway inside of Char. Once a striving symbol of love and peace, after the Hammer Strikes, the inhabitants turned to ash, and ash storms began to move in. A heavy ash storm has rolled in, leaving your sight to a minimum. And to make matters worse, the Ash People could be mistaken for real enemies, posing very suspenseful gameplay.
Fuel Depot- Even though Summer has began on most of Sera, Fuel Depot returns with it's snowy roots. The Gas Tanks have been frozen over, causing one threat to be over with. However, much of the map is now decomposed, leaving more threats from the Hammer of Dawn to be caused. The map is now at night, as well.
River- River was once one of the most beautiful sights in all of Sera, but an Imulsion Pipe has leaked and the leaking Imulsion can be a cause for death. However, when not in use, the Imulsion will be out of use, giving safe passage to those who will take it.
Security- Security is a top secret COG Outpost that kept the secrets of the Sires. Now in the night, the map is still the way it was, Laser Wires and all. In Horde, the Laser Wires are activated by a Command Center.
Tyro Station- The final remake of this DLC, Tyro Station would return, but this time, the Train is on a random loop: no 15 seconds apart, it could be 5 seconds after, it could be a minute. It would make the gameplay more exciting, in my opinion. Also, a larger fog has rolled in, and the lights are the only thing that can guide you, because the train makes less noise.
Samhain- Samhain is a city block in Ephyra that was once a party spot. However, once the Lambent Plague began, all of the Stranded there became Formers, infesting the map with more and more of them. This would pose a threat as well as the enemy teams. The Formers wouldn't count as weapon kills to avoid boosting. There is a Mortar in the middle of the map, which proves to be very deadly in the narrow alleyways
Power Weapons- Mortar, Gorgon Pistol , Breechshot 
Ground Zero- Ground Zero is the center of the Hammer Strikes of Char. Once on of the largest cities in Sera, after the Hammer Strikes, the buildings are completely destroyed, and the Ash Figures are still there. A Hammer of Dawn is found in the center of the map, and the collapsed buildings make a sort of circle around the Hammer of Dawn.
Ilima (OverRun)- Ilima is a beautiful government building in a Seran city. After RAAM and his Elite Squad took apart Ilima, a large amount of Elite Weaponry was found. In the garages next to the government garden, there are Elite Sawed-Off Shotguns for anyone to take. In the center fountain, now bloody and dried, there is a set of Kryll Grenades for the lucky user to find them. Inside the building, a Scorcher is found, making a strong CQC powerweapons for the small maze-of-a-garden outside.

Why have unlockable characters and weapon skins? Epic should give us unlocks to give us more to accomplish.
Why have them be so difficult? Because Gears of War and Gears of War 2 had difficult, time consuming achievements, not achievements unlocked the first day.
