Sudden Strike 2 Expansion Pack Hidden Stroke 2, a game with timeless gameplay. It works as a standalone, so you don't need Sudden Strike 2 to play it. Operation confirmed on Windows 10 and 11. I mistakenly thought I had lost it during a move and repurchased it, but I found the original disc, so I'm putting it up for sale. It works standalone without Sudden Strike 2, and by downloading single maps created by users around the world from the internet (done individually) and placing them in the appropriate folder, you can play at least 300 maps. The value is truly worth a lifetime. As shown in the photos, there are two shallow scratches on the disc surface that are hard to see, but I was using it until recently, so there are no problems with the operation. There is also a manual, so it's easy to play even for beginners. There are more single maps created worldwide than for Sudden Strike 3 and 4, and it's easier to play, so this is a highly recommended software. The operating environment is shown in the box photo, so please refer to it. It works on old PCs. I think there are few PCs these days that don't meet this operating environment ^_^ The used market price ranges widely from around 7,600 yen to 30,000 yen, but considering the abundance of single maps from around the world that can be downloaded and played from the internet, this is not expensive. This time, I will sell it at a significantly lower price than the used market price, so it's a great deal♪ Let's experience the profound World War II ^_^ If you have any questions about the price or anything else, please feel free to ask.
