Well as current plans go, it's gonna have the latest (private) updates to the original bugs, which will include Poison, and four loadouts for the MAS side (Two exclusive loadouts being the Orb Launcher and a generic 'Security' class armed with a P90). Additionally, MAS troops will be armed with a Sandvich to simulate the (unpatented) MAS Rechargable Health System. Simply prime and inject, and you will be filled with 200% Adrenaline and nanobots to but you back in the fight!*
Also, the base's contents from the ground up: Storage (the starting floor for bugs will technically be in the center of this, with vents leading into the facility), the labrotories the bugs first broke out of before making thier central hive, a secretarial floor and research/development wing (including giant doom lazer), and then finally the surface access. If even one bug makes it past the MAS drop point, it's victory for da bugs. Think Jail RP for the type of gameplay. While the combat bugs like Scorpion and Worm keeps the MAS troops busy, the smaller bugs shall focus on breaking the facility to make escape possible/easier. MAS can use elevators to travel through the facility floors themselves.
*side effects include nausia, heart attack, cardiac arrest, stroke, arthritis, joint pain, toxic shock syndrome, and halitosis. Rechargable Health System is not for everyone, consult your doctor before use.
