Use the arrow keys to move the Dalek. Press the "O" key to "open" the dalek and release the Kelad true form. Use WASD to control the Kelad. To exterminate, press space. Yeah, it's just a start. Don't worry, I'll improve it.
BBC has the rights to Dalek, Doctor Who, and EXTERMINATE! This will be updated as constantly as possible. You probably will find all these glitches. But hey, it's BETA. Now, before you go exterminating, I just want to say, all of classic and new Doctor Who is on Netflix. Go check it out!
