Requester: PROGTECH

Reward: 52000

Theater of operations: PROGTECH Lab Block 7

Objective: Defend all gates

Safety Level: 91


An emergency situation has arisen. Our Laboratory at the center of the city is under attack by unknown forces.

The invaders have divided into several small groups and are attacking via different routes. We assume their target is Elan Cubis' Lab.

There may be some connection between these units and the ones that attacked out Marine Lab, but we aren't sure.

All 4 Gates leading to the Laboratory are located in Block 7. These key locations must be defended.
