Side Ops are companion campaigns to the original C&C Red Alert that explore what was going on at the other fronts during the Allied and Soviet campaigns. There are 32 missions in total, with a prologue and epilogue for both sides.

Side Ops is now at Version V1.1

Now included in this collection are:

Side Ops - The Black Operations:
Europe is on the cusp of war; both the Allies and Soviet must do everything they can to gain an advantage over their enemies. The Allies are deploying their agents from the Office of Secret Actions to sabotage Soviet advanced weapons development and the Soviets are working with Socialist freedom fighters in disenfranchised countries, instigating social and political upheaval across the world.

and

Side Ops - Mediterranean Supremacy:
The Eastern Mediterranean is vital to the war effort, so the Soviets are attempting to take control of Cyprus after securing the Levant. Meanwhile the Allies are using a recently liberated Greece as a springboard into Anatolia, where they hope their Turkish allies can turn the tide in their homeland.

and

Side Ops - Ice Curtain:
Norway, Iceland, Alaska… The Second World War has many frozen fronts to spill blood on. Fight over vital resources in Svalbard and Iceland, use Commandos and Paratroopers to strike at vital enemy infrastructure, and vie to secure the Bering Sea as the Soviets look to invade Alaska.

I am always happy for people to offer criticism, and am willing to make updates and changes as appropriate. Have fun playing!
