"Casual"

[Squid]

Started campaign map 4, selected enemy CASUAL. Got r*ped in 10 minutes before i even had the chance to upgrade workshop to level 2.

If this is casual, WTF is normal mode?!

5 Minutes. *giggles*
I cropped my hair, but it is a lousy NPC.
Just expand fast to the "entrance" and Research on Arrows 1+2
If done fast, the Rest isn't needed to explore anymore.

I found out the best way on Casual is just to expand toward them as fast as you can. Build as many towers as close to them, immediately.
