Update:
I just added a new mode to Illum: Wavemode
I think everyone knows how that works.
You eighter play as Rebel:
or as Luke:
Each wave lasts a minute until the next one will spawn. A timer will show you how much time you have left (at later waves 60 seconds will get pretty close).
For now there are 8 waves. But I plan on making atleast 10 to raise the difficulty more smothy.
I didn't modify the health of both classes. So it can get pretty intense in the last few waves, however, I don't want you to be crouching in some corner.
It's good to stay at the base since there are a health and an ammo droid.
I thought about randomizing the waves a bit, although but I'm not sure yet.
Heres a pic of what may await you:
