How I should be able to kill enemies and level up (noob)

[Elmo]

Best thing to do is hang back, let some commandos take all of the bot agro and just do some cheeky side swings on the bots if you feel brave also If you haven't already, go into your game settings and turn block mode to automatic. I did not know that automatic blocking was a thing on this mod for a very long time, which made my leveling up even harder :L

If you see some medic boxes on the ground then i would highly suggest being the servers medic. You can refill med boxes at refill stations so you can spam heal on certain maps. You become less squishy at around tier 3 so until then just be as useful as possible to the team and collect as much xp as you can

If you haven't already then i would highly suggest you read some threads like

Hope this helped!
