[Steam] I've been seeing this a lot on Steam lately... Recommended new FPS, Warthogs

The Korean reviews were mixed, so I just dismissed it as a bad game... but I guess that's not the case? It's in Early Access and costs ₩47,270... There's no story-driven single-player, it's mainly multiplayer... My deputy manager who likes shooting games might enjoy it...? I tend to get stressed playing FPS with other people, so I don't play those. I enjoy single-player FPS at my own pace... but trying to play single-player Tarkov is too expensive.. Should I play Metro, which I bought but haven't started yet? For FPS, controller vibration is way better than keyboard and mouse.. Seems like a lot of people don't know this... Of course, you might get angry trying to aim... but controller aiming is comfortable once you get used to it ㅋㅋ Controller aiming is when you fix the R stick and use the L stick to move and aim.. ㅋㅋ Watching gameplay videos makes me want to try it... I wonder if it'll be supported on PS too...?
