As big fan of classic fps aka doom and serious sam and also a metal musician I can definetly say: music - its the only thing why you will keep playing.
everything else is terrible.
Weapons is on the unity indie game level.
Rhytm sometimes is gross. I am musician for 5 years and cant believe that im losing metronome.
Level design is terrible.
Boss fight is boring.
They used Dark Tranquillity vocalist's song almost 8 times in story.
Best OST with Serj Tankjan and Alissa White-Glass.
Wait for sale.
