Science fiction art style, romantic charm of galactic nebula, tough fighting of madness, this is the STAR DEFENSE MISSION, a super classical real-time defense game. You will meet machine army in flood. Defense! This is not about the amount of the enemies, it all depends on your intelligence. That’s right! You are the key of this battle, you can defeat all enemies only by utilizing all energy sources, terrains, and your most important technologies. Guard your crystals, they are the hope of your victory, the source of your strength. Come on, believe in yourself, and beat the evil Sinu with your homeland.

Game Story
The story of STAR DEFENSE MISSION happens in the Lightsource year 9-2. Sinu has ruled the whole galaxy, but some humans who yearn for freedom escape from his sphere of influence with a great number of energy crystals. They build small space bases on the edge of the galaxy, grouping the rebel force. However, Sinu has scented out the plot and sent out his elite squad, the Dark Order, to loot the crystals and extinguish human’s last hope. Though they successfully break into the base, they are under fierce attack from defense towers. A defense of the crystal just begins.

Omg! So good, but flawed

I love this game!! But it's soo flawed. There may be some confusion on the in app purchases in other reviews so here's my issues with the game. To upgrade the special abilities of the towers in the upgrades menu you need to level up then you get two points to spend on whichever properties you want. The other option is to pay real money and get the level up. This gets expensive when each level costs 2 real world dollars or five for ten dollars. It's in my opinion too expensive. If they made it cheaper I'd be more than willing to support a great developer in hopes of getting a sequel. I hope enough people support this game and its developer to warrant a sequel because this really is a great game. Anyone on the fence just give it a try. I know you'll find it addicting


One of the best free tower defense games!

Currently at level 36 normal difficulty with base level 80 with 80hrs of game play and not a penny spent on in app purchase!! I really like the bonuses twice a day just for launching the app. Sometimes I get bonus items that really helps passing a level. I usually save up on resources by just playing the levels that I can pass without using any items at all. Then go all out when there are bonus items :) Still haven't touch the "hard" levels yet. Thank you for making such a fun game truly free!!


Really Outstanding Defense Game

Stumbled onto this game one day and have been loving it ever since. The graphics, sound and gameplay is second to none in this genre in my opinion. The in-app purchases are helpful, but not required to enjoy the game and/or make progress.

Aside from a couple of spelling or grammatical errors in the menus and text I can't really find anything negative to point out.

Get it now!
