I'm a doctor, not a mechanic
An Assault Info Actor allows for that cool little screen that appears when you press F3 during a UT match. It allows you to set up screen shots of each objective and put a short background to your level.
Assault Info Properties:
The total number of rows to show on the HUD when the Assault Info is displayed. This denotes the number of screenshots that will be visible.
Allows you to describe your level objectives. It may be possible to use multiple actors to make more objectives, the scroll bars in the window seem to work.
Assign screenshots that will be shown in the display here. Import these like your average Screenshot UT into the MyLevel package, ensure to give them meaningful names.
There isn’t a lot else to be said really, the code just declares the class and defines some variables.
