Shield World (level)

Shield World is the tenth level of Halo Wars. The level is set on the same planet as the previous mission, against the Flood. The main mission is to rescue three different teams by killing all the flood in the way between the firebase and the units. Team Alpha reward you with a Grizzly tank, Team Bravo reward you with an Elephant, but when you try to rescue team Charlie the pelican is destroyed. The Spartans say they'll make their way to the base to be picked up there. The normal time limit is 18 minutes, but a side mission which gives you access to the special Gremlin unit that involves placing Gremlins in different corners of the map will buy you more time (About 22 minutes for all four of them.)
