[Nostalgic Game] Special Soldier

Does anyone remember a game called Special Soldier? I used to play it a lot during my elementary and middle school days. Back then, I played with my siblings or neighborhood friends, and we'd lose track of time. It was a simple mobile FPS game that I'd hop into whenever I had free time, and looking back, I think it had its own unique fun. Especially betting with friends on who was better was quite a memory, haha. Unfortunately, Special Soldier's service has ended, so we can't play it anymore. Sometimes when I think about games I used to play, I feel like I want to play it again. Nowadays, there are many games with great graphics and fun gameplay, but maybe because it was a game from my childhood, the memories of Special Soldier are hard to forget. Is there anyone else who played Special Soldier in elementary school like me? I'm also curious about which mode you liked the most back then!
