Castle Corp

The last time E4 towers came under attack we just poured boiling hot oil onto their faces and laughed heartily as their eyes melted. Had they had the ability to fire themselves at us we might not have been so amused.

Castle Corp is brilliantly animated - of course: it's Nitrome - and the action is engrossing too. You ahve to use your team to kill off the enemies, earn money and then buy further skills. Mothers of invention.

You just need the mouse to get things going here.

Where possible, release your captured friends, as this will give you more options for future levels.
