I don't understand the hate this game gets. It's everything it claims to be.
The gameplay is smooth, the graphics blend the style of both games quite well and the soundtrack is awesome (tho it would be even better if it was a mashup of Half Life and Hotline Miami style instead of just synthwave, or maybe synthwave remixes of the Half Life 2 OST)
The gravity gun is fun to use and I don't think it being the only weapon hurts the gameplay. It's already way closer to Hotline Miami than Half Life 2, if we could pick up enemy weapons it would straight up be Hotline Miami with different textures.
I also like the idea of the game taking place in a City-17-ish Miami.
My only problem was the reaction time of the enemies, they will instantly flick and shoot without any delay even if they are facing the opposite direction. Zombies are way too easy to deal with. Gravity gun is also not a guaranteed one hit kill but it was also how it worked in Half Life so it's fine.
It only ever crashed once in my entire playthrough on a Win11 machine.
I would recommend it to any Hotline Miami fan, tho I'm not sure if I can say the same about Half Life fans. Very good game overall :]
