I saw a fair number of anti animal stuff there. Despite Spino's massive health he'd go down pretty quick with upgrading units on him. I wonder if there's some good strats on luring critters like that into the enemy base. Like using a ninja or something to finish the nest off from a distance, run, then unlock the enemy gate, cruise through and invite the spino or horde of evil into the camp. I'd love to pull something like that off someday. I'm up to my chin in Neverwinter Night stuff at the moment.
I really wanted to use it on the level you get Warden but you so much as move anything into the SEAS detect zone and you're had. On a normal map or some other level it might be possible. The city defense level comes to mind. You got a bunch of T-Rexes near the SEAS base. Its possible to unlock the gate, run down, destroy the nest, and have the rexes chase you into the SEAS Base. Though, I'd use this as more of a diversion than an actual attack. The real deal would come during the diversion so the Seas have an angry Rexes at the back door and the 'araworld Liberation Army' at the front.
