seems like quite a powerful weapon. I'm guessing that the bullets don't die or have a longer lifespan than the launcher shot. if the worms don't have a lifespan then there could be problems with enemies just running off once a worm is chasing them.
All shot-types will have a life timer. Can't balance them otherwise.
I'm already planning on a cap animation for the beam. It's a bit unfair getting lazored off-screen and without a range limit I can't balance it against other weapons. It might be cool to see it earlier but at the moment it's OP and has a massive AI presence.
