On your journey you’ll meet the worst that the galaxy has to offer, and it will be up to you to choose how to deal with them. Do you help out those who have given up the fight? Or do you take shortcuts and gun down anyone in your way? As you learn how to fight the invaders you’ll gain new skills, but limited resources will make it impossible to save everyone.

“Easily the most engrossing book I've read in years. It's a near perfect throwback to the old books where you are the hero.”
“This gamebook is absolutely brilliant. The scifi setting is highly detailed and well thought out.”
“Heavy Metal Thunder is, by far, the greatest book I have ever read.”
“...it's a long, extremely well-written story with tons of choices. Very re-playable.”

-- Pocket Gamer (Silver Award)
"The kind of deathly sci-fi that you’ll enjoy if you liked Dead Space or the frightening moments of desperation in Gravity."
"Heavy Metal Thunder is a cruel and unforgiving gamebook. It bashes you against the debris of space over and over, and is happy to leave you at the mercy of all manner of terrors."
"The whole thing is presented brilliantly. The skill check and fighting interface in particular makes tapping the screen to stop some dice feel surprisingly futuristic."
"It's refreshingly grim, and manages to keep you entertained throughout its hefty running time."
"Fans of the genre thirsting for something a little darker should definitely give it a look."

-- Pocket Tactics
"A big sweeping pulp sci-fi story of impossible odds and encroaching insanity."
"I had a lot of fun with Heavy Metal Thunder, and look forward to future installments."

Possibly the best thing ive ever downloaded. And I still come back to it.

I’ve come back to this game/story and i still believe its the best thing I’ve ever downloaded, even after about 2-3 years. An unbelievable game, play with quality headphones and at night for near perfect immersion.

Amazing. A must buy.

This game is so good. Unbelievably good. You're doing yourself a disservice by not playing it already.

Great Story, No Sequel

The game and story are phenomenal. The skills and items you acquire actually have a noticeable impact on gameplay. However, there used to a be sequel to the game available on the App Store and they yanked it from existence for apparently no reason, so I am removing a star for that.
