Set in the year SE 3256, the player is thrust into mankind's first interplanetary war between the Earth Alliance and the Ares Confederation. As the promising captain of the experimental dreadnought prototype, codenamed Sierra. Your sole objective is to help turn the tides of the war, utilizing the ship's advanced combat systems, flexible energy allocation and optimized platform deployment capabilities. To the captain, the core principles of prudence, guile, resource management and patience are essential to survival. The technology incorporated in Sierra allows it to explore multiple paths to victory: evade and assault enemy ships in classic broadside warfare; research armaments and upgrades to outgun the enemy fleet; or outnumber them with remotely-controlled weapon platforms. Rout the enemy’s armada in order to quell the rebellion and save Earth from the corrupt colonials.

The full game page of Operation SD: Space Defense including its downloads will be changed totally to the rebuild version as soon as it's completed, so the previous version of the game will most probably be overwritten entirely.

Sorry about that, thanks for pointing it out. I can't believe I let such an obvious bug slipped up. I'll have this fix as soon as possible.

Update: Sorry for the delay. The patch is up now, it should fix the stage data from not saving properly.

This game is going to be as is. We're planning sequels, though.

I feel like there should be Mecha in this game, lol. I think it's the music from the video, and how the game looks. Gundams? lol

looks good, I might get it.

I'd also like to see animated chat avatars. give the game more of a Star Fox feel to it.
