“HES has one of the smartest concepts for tactical space biffing that I can remember seeing.”

"It requires a different mindset to ordinary turn-based strategy games, which makes it a unique and worthwhile experience."
Indie Juice

"It's like the Kobayashi Maru test where they have a scenario and you have to figure out a way to beat it."

"There's nothing quite like it!"

"... a really fun and tough strategy game ..."

CLASSIFIED: Unified Earth Defense Forces HES program

In 2312, first contact with the Navassian extraterrestrial species was established near the Deltria system. For 5 years we have been observing this warlike race while maintaining a wary diplomatic relationship. Growing tensions over ownership of the minerals of the Deltria system lead to the formation of the Unified Earth Defense Forces.

Facing overwhelming odds in a direct military conflict, the UEDF introduced the Halting Extraterrestrials Strategy, or HES, training program for all officers. The simulator presents likely combat encounters based upon observed Navassian tactical data from previous engagements. Recruits call this program the Human Extinction Simulator due to the extensive and often catastrophic scenarios depicted. While most find this amusing, some fear that it might be the actual name of the program.

Welcome to the meat grinder, Lieutenant.

Unfortunately the Adobe AIR version I'm using is a version for which Adobe stopped supporting Linux. A Mac version should be fairly easy to come up with but I have no idea why Adobe stopped supporting Linux and it's a shame :(

So it's sadly not planned at the moment as it would require a complete rewrite on another engine. Nothing is impossible but let's just say that for now I really can't promise anything related to Linux.

Any plans for a Linux version?

Well keep it up and I hope everything keeps coming together and getting better! Good luck

@Giant Cheeseburger I'll give you that making trailers ain't my expertise so I probably miscommunicated what the game is about to you.

These icons are population markers and only appear in specific missions. As the planet is attacked, population decreased and the "icons" get smaller. The game is still in beta so yes I hope to improve how these visual aids are looking.

That's only for missions with a planet. If you check the beta (link above in description) you'll see these "icons" appear only in 1 mission so far.

As for the name well, some like it and others don't. One thing for sure, people remembers it :)

"You should know without being told anything"

I disagree. That's part of the learning process. As a single dev I have to wear all the hats and at one point it's inevitable that I make mistakes. People point them, I take note and try to do better the next time.

I actually enjoy when people suggest nice things to improve my work.

@Over00 I mean that as somebody who has helped design games and seen the process, I know that having little icons representing humanity on a planet in the background is lazy. I think you guys could do much better -- something that actually feels meaningful and exciting -- but instead you decided to title your game after what basically comes off as a joke. Are we supposed to care about the little humanity icon, just because you call it "extinction simulator"? Maybe you recognize that nobody would even KNOW that it was supposed to represent humanity being destroyed unless you named the game after it... You should know without being told anything.

@Giant Cheeseburger Just to clear things up, the "shooting at the planet" is actually part of the game (real gameplay footage) and not just something done for the trailer so I'm not sure what you mean by it being "lazy".
