Gigantic X is a fast-paced and responsive top-down sci-fi shooter with a strong focus on action gameplay. Earn your spurs as a space-faring mercenary by clearing habitable planets of alien parasites, battling deadly monstrous creatures, and helping defend the ever expanding frontier - zones of constant conflict and action.

Your success will depend on collecting and equipping the right gear for the right job, and even more on your ability to learn attack patterns and respond accordingly. As a top-down sci-fi shooter, Gigantic X will require fast reactions and responses from its players. Your skills, gear, and knowledge will only be tested more and more as you climb the ranks.


In the interstellar age, the human race is expanding throughout the galaxy. Expansion does not come without resistance, however, and the Galactic Alliance is in constant need of brave soldiers who are willing to fight for the continued growth of humanity.

Three drifters band together to answer the call, figuring they might as well split the bills. They’re not particularly fond of the Galactic Alliance, but cash is cash. Besides, they don’t know of much else besides shooting and fighting, so they might as well get paid to do it.

Guns, Gear, and Glory

I have never taken time away from playing a game in order to make a thoughtful review simply because there has not been a game worthy of my powers as a wordsmith. Well, let me tell you, this game has had me head over heels since launch. There are a multitude of weapons to choose from between the three characters and they each bring out different play styles. The gear adds nice facets to the game bringing out the power in some weapons or adding a bit of survivability. My personal favorite, well, 30% attack bonus for never getting hit ;). But wait, there’s more! That’s right, co-op. There’s different difficulties or challenges for all players ranging from fending off treacherous waves of enemies to battling multi-phase bosses. The early coop missions may be easily defeated but the later bosses may require some practice takes. My advice is this: you get the guns, you get the gear, and you get the glory. See you on the frontline -SpamMusubi(NA)
Many people speak of how you can only play so many missions per day. But, with some in game currency I can buy 100 energy once every 3 days or so, and 40 energy once every 2 days. So I save up my energy until I get a day off and it works out.

Great game but too long

The game, for being out for a short amount of time as of me writing this review, is a great game. Firstly I have to say that other than these complaints this is a great game and would highly recommend people to play this and would love to see what this game will and could offer in the future. However, there are a few things that should be shorter. The main thing is the energy system. For one I am not a fan of these systems and know they are just used to make money and are bad for the consumers. That being said making it be almost an entire day to completely refuel is unacceptable and should be shortened to 4-6 hours on the high end. Another thing is to make prime chips more common and more ways of getting them. Finally there are still a few bugs to work out (like any game) but there is currently one with frontline where challenges to get hacking credits wouldn’t be rewarded. Hope my expectations will be met and exceeded in the future. Thank you for the great game I just can’t get enough of.

Honestly one of my favorite games but

I have a request which may or may not happen in the future?! I am hoping the developers of this beautiful game add some PvP multiplayer if you want you can add it with some aliens so the game doesn’t lose its feel to it. Definitely more characters and definitely a create your own character type of thing should be added to the game. I really do enjoy this game I absolutely love space. My favorite character right now is Scardy! One last thing I don’t know if it can be changed or not but your name in the game you should be able to change it once for free and the second time you have to pay or something? I don’t know, I say that because I really wanna change my name without starting all over. But anyways I really love this game has soooo much potential and it’s phenomenal! I will definitely never uninstall this game it’s a gem to me. Thank you~ Jonathan
