That was my first attempt... solo. I was so upset. Why the freak did I not walk towards the panel to shoot it more!? The ufo was still there above the portal! sigh Whatever. Map: Zombies in Spaceland store.playstation.com/#!/tid=...
Tip: Start placing the speakers from spawn and go left to right. So spawn, Journey, Polar Peak, and then Kepler. That way your colors match up to the corresponding areas. For example, journey is blue (blue spaceman), polar peak is green (green yeti), kepler is red (red alien), and spawn is yellow (Idk why, I guess just default). So when the ufo displays the colors you can think of the different locations that the color’s correspond to. That should make things easier. 👍
