The laser sub machine or laser sub is the strongest weapon in the game dealing 45 damage each hit and having a 30 shots in each laser sub. You can reload the laser submachine with cells.
Getting a laser submachine is very hard and I've only done 2 successful speedruns and those are the only 2 speedruns. Speedrunning requires some luck as well. Both speedruns I got lucky. Game : Devast.io Developer of game : LapaMauve This game is also free to play (No P2W stuff :3) and you don't have to pay to play it. The downside is that the game does not work on mobile.
