On the first battle I played as soon as Gauss was released everyone was using it and it became overwhelming too keep getting hit by everyone and I couldn't see where they were since there is no laser. Also everyone was also using double damage and they kept one-shotting my m1 viking so I just gave up and used titan.

It is not M4 Gauss I think it just got jumbled up since the M1 Gauss is labeled as M2 and M2 Gauss is labeled as M3 I did not notice that, lol :)
