Sturmtiger M??

so either last night or the night before i was watching zeno's stream, where i then saw that he had somethin called the sturmtiger m or sturmmorser m. he never showed it but it looked cool as hell. and it got me thinking, why do the devs keep cool stuff like this away from the playerbase? is it too op or do they just not like us enough to give it to us.

i do love this game tho and all that it is and im sure they have a resonable explanation.
