This is a great little game like all the ones from the Trese Brothers. I've bought all of them just to support these guys for the ones I really like. They have gotten more and more polished in their games as time goes on and add new content and continue to balance and bug fix the old ones. These are really mainly bug pictures with a few fun ones mixed in, but look up their games on Steam, Google apps, Apple store and Amazon.
The Sentry Turret holds its ground against massed xenos.
Everyone dies here in Ironman, the Captain at top either explodes from heat damage if he shoots the xenos or the xenos run up an kill him.
It took massed firepower to get off the ridge to the south as several spawning xenos with flankers came to call and the firefight isn't over yet.
Overwatching the Captain.
