Hello, dear @ahmedhayat
You brought me a lot of memories with this post and the pictures, I loved this game a few years ago. But I had completely forgotten the campaign and the story part behind it.
You described it very well, it made me want to download it and play it one more time haha, seriously, thanks for refreshing my memory so faithfully. I was going through the same thing of trying not to use the hero at all so that the campaign wouldn't be at risk.
I send you a big greeting, and congratulations for this game post.
