Ambush

A small group of Federation land forces was transporting resources in the Mars landscape. No hostiles expected, so only two Exosuits [link] and Hardpoint robots [link] were making the scout of four Mobile Towers [link] and four Mobile Wall trucks [link]

But them, unexpected, they are attacked by vicious Elder Things, a small strike force of three Eyes [link] and two HKs !

Of course you cannot see the lasers, so the Elders have the Federation forces surprised as they try desperately to protect the trucks and the towers...
