i have a few ideas:
1: give them their proper voices from there respective episodes, or make em customisable, like the classic imperial voice, the classic renegade voice
2: make drones and soldiers follow and guard the supreme, and give the supreme more roaming distance, which allows entire squads to scavange and hunt down in a pack, as they kinda wander around
3: maybe flying daleks, allow them to fly around, this should only occur if their target is much higher than they are
4: give the daleks a small explode effect when dying, like in the show, would add alot more effect rather than just stopping and all their limbs flopping down

these are just ideas / request, i dont mind if ya dont add em, just seems cool to see
