Why is shootergame highrise global gravity set to -2000?

We’re on the process of tweaking our FPS and wonder why the Shootergame Highrise global gravity setting is set to -2000?

We made our own levels and by default this value is 0. Epic, you usually do things for reason and I want to know why this is done in shootergame?

Any chance to get some input?

We found that physics didn’t look right until we set our gravity to -2000 as well. Falling objects and ragdolls looked ‘floaty’ like they were underwater or something.
