Armored Core 2
The true sequel to the original Armored Core game. You'll be thrown into the world of AC mechs and you'll have to fulfill the missions given to you by various companies, each of which comes with a hefty payment. Once the mission is completed, the money goes towards upgrades and repairs for your mech. The collection of items with which you'll be able to upgrade your mech is full of weapons, defense systems, missile packs and guidance systems to increase accuracy and speed. Certain missions require a specific upgrade to complete the mission correctly, so it's important for your career to spend the money wisely. When your mech is ready to fight, you'll also be able to compete against a friend in the arena mode, where you'll be able to fight in huge outdoor areas for as long as you want.

Sixty-seven years after the events of the Subterranean Era in the previous games, Earth's second largest corporation, Zio Matrix, acquires plans for a research project on Mars dating back to before the Great Destruction. With the help of these plans, Zio sends a research team to Mars to start the terraforming project, which adapts the Martian surface and atmosphere to Earth. Other companies learn about the project and join Zio Matrix. They bring with them the competitive environment that prevailed on Earth and work with the mercenaries of Nerves Concord.

But in the ensuing chaos, the Frighteners turn against the government, assassinate the new leader of the LCC and take control of the powerful Disorder technology. The player character has the task of opposing them and saving the human population of Mars.
