I have 3 ideas for new grenades that could be added. We have some good variety with the guns, but only 3 grenades.
1: corrosion grenade. It's pretty straightforward, we already have a corrosion status effect in the game so why not make it a grenade?
2: bees. I just think it would be fun to have a grenade that spawns a swarm of bees.
3: gamblers grenade. It's a grenade that recharger faster than all the other grenades, but the drawback is that it randomly chooses one of the grenade status effects. So you can use the grenade more, but you risk throwing a grenade type when you have no upgrades of that type.
