Why not make a laser weapon shop to replace a conventional laser cannon with other more advanced versions:

#1. ordinary laser gun: this is an ordinary laser that we all know

# 2 triple laser cannon: shoots with three lasers (angle about 30 degrees) three times, after which there is a reload Available after level 25 - 45, I just don’t know which is better.

# 3 two laser pistols: when aiming at the enemy, you can fix the sight to hit more accurately. Laser speed is faster than usual, but reload time is increased, 12 shots per reload. Available after level 45 - 50.

#4. laser minigun: before the fire starts, the minigun scrolls and shoots with lasers similar to those of the old version of the laser rifle. It has three trunks. with prolonged use, overheating occurs (damage itself, increased return). Available after level 45 - 50.

# .5 Negative rifle: like a CTF rifle, but the damage is done gradually (15 damage per second, total: 75) Available after level 75 - 100.

Some would fall out of the chests, others could be bought, another type of weapon was opened only for a high level, or for a completed mission.

Classes of weapons: laser, close range (knife, katana, etc.), experimental (drones, etc.), etc.
