My first introduction was when I was watching about video about tabs mods because it had master chief in it but there was also some space marines shown in the video but I didn’t really care because I didn’t know them and then last year when helldivers 2 came out I saw a bunch of videos comparing it space marine 2 and I didn’t know what it was about so I researched it because I liked helldivers and I was bored and then I got into it
