Your job is simple: Complete the mission. Each day, you wake up with a new mission, forced to descend into a strange and deadly building, called The Monolith. Before each mission, you are able to choose to bring a weapon, and a tool. You must work with your team to ensure you have the proper equipment for the job. Along the way, you will need to scavenge for resources to keep you going, as well as new weapons and tools. Play in either ENDLESS mode or WORKWEEK mode: ENDLESS mode will continue on forever, challenging you and your team to see just how much you can handle. WORKWEEK mode is a set of 10 missions given out weekly. Each day gets harder and harder, with new threats appearing later in the workweek. You can view the missions ahead of time, allowing you to plan ahead and bring the appropriate gear. Work together to ensure survival. Teamwork is the only way to survive the dangers that roam within. One wrong move is all it takes for things to go wrong, and for your team to die. Coordinate and plan ahead before taking action. Always assume the worst, and use every tool at your disposal. A team without a plan will be quickly killed, as the dangers waiting below are relentless and won't hesitate to rip you apart. Ensure you have backup plans for when things go wrong. Which they will. The insides of the Monolith are a frantic, unpredictable monstrosity. Things will go wrong. There will always be something you didn't see coming, so you will need to think quickly when things don't go according to plan.
