I had never played this. I've played the first game on the Gamecube a bit, but not huge amounts. I remembered it's a real-time strategy game where you control units directly. What more did I need before launching myself online?
I took immediate control of a battleship, and started shelling the enemy ships. This seemed to go well until my other units and my colleague's units started to get a bit too close to the enemy. I think I sank one of my own ships before I worked out how to change which unit I was controlling.
Having been left with a solitary infantry unit, I was glad to be given reinforcements when I landed on the beach.
Many of them didn't last long either. I was instead left to blunder through the level following my colleague in arms, and even that didn't go to plan. I tried to help a little too much, and got all my units killed. Luckily there were some prisoner of war camps nearby that my men were rescued from.
A final push up the hill, and I completed the mission. Easy!
