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.

So here we present to you, the build that you've been waiting for: It is now designed to let you play the game continuously and is now a lot easier to understand how Sierra Ops is played - hopefully!

PC :
Direct Link - Innomenpro.com

Mac :
Direct Link - Innomenpro.com

Linux :
Direct Link - Innomenpro.com

Mediafire Folder:
Mediafire.com

Known issues:

  • Sometimes, you can't enter the Resupply Station. So what you should do is simply enter the LITE simulation, and escape right away, and then return to the station.
  • The free camera mode sometimes has issues with the platform mode, making it hide the mouse cursor. The solution is to just alt+tab back to the game to regain control of the mouse.
  • The Mac/Linux release hasn't been tested thoroughly, as well as Win8. Volunteers are very welcome to try the game, and report the problems to us by sending an email to jason.m.cheng@gmail.com.
  • The pause/battle menu is just a placeholder, but the window/full screen mode button there works.

Additional Information:

  • The Harbinger cannon requires Level 20 weapon and Level 20 Particle Capacity.
  • The abilities in game uses the shortcut keys E,R,T, but you need to learn the appropriate skill for it in order for them to work.
  • We've also made the Leviathan more active and has a second mode at 30% hp and below. If you can record your battle with the Leviathan and has managed to defeat it, the first three people to upload at Youtube will win an all digital bundle! (It's the 80$ perk at our IndieGogo, containing exclusive digital works such as the game design book, HD wallpapers and Original Soundtrack - Indiegogo.com )

Hello, can you tell me any other details about the error you encountered? You can do this by checking the errorlog.txt file inside the Content folder where Operation : SD is installed. thanks

Sure. Here is a part of it

7/9/2013 12:48:49 AM : System.IO.FileNotFoundException: Could not find the file C:\Users\Owner\Documents/Innomen Productions/Operation SD/ShipDataFile but found the directory c:/users/owner/documents/innomen productions/operation sd/ Did you type in the name of the file wrong?

Go to C:\Users\Owner\Documents/Innomen Productions/Operation SD/ folder and check if the ShipDataFile is present there.

If not, go back to where Operation:SD was installed and go to Content/Databases/ folder and copy the ShipDataFile from there.

You might also want to copy the MissionDatabase.csv file from the Content/GlobalContent/ Folder if the said file is not yet present in the operation sd save directory.

Alternatively, you can run the OPSDSettings.exe (it might give an error, just press continue) and press the ResetSaveData button.

That is odd. Try re-installing the game to see if it fixes things up. The error indicates it cannot load/find certain resources. Also are you installing the game from the stand alone build or the Desura build?

I also seem to have the half screen problem where the videos are supposed to play. I suspect an XNA problem seeing as we made the game on XNA 3.1 it probably didn't aged well. You can still access the tutorial videos inside the Content/Transitions folder as wmv files.

Hmmm, if you don't see the Transitions folder inside the Content folder then something must have gone wrong with the downloading/installing process.

Also, there should be 3 files inside the Operation SD savedata folder (the one inside your documents folder) namely ShipDataFile, MissionDatabse.csv and ErrorLog.txt.

if you see all of them there and you still have an error then try downloading standalone version. I tried installing via Desura on my end and it worked out just fine so I am quite stumped at the moment on what the problem on your end is XD.

Hmm, can you tell me what is your video card? This error usually happens if the video card of your current setup does not have at least pixel shader 2.0. ( A requirement of the XNA framework)
