I was hoping to add a little content for Halloween in the next update (although it's not a promise).
If there are any important bugs you would like me to focus on, be sure that they are reported on forum.
If there are any reported bugs, which you think are especially important, please post in their forum topic to make sure I don't forget about them.
If I remember correctly, last year Pandorium balance was way different.
Grenades and Explosives have different purpose now.
Grenades are meant as an AoE weapon against groups of light enemies.
Explosives are mostly meant to situationally help out with Nests extermination (although without replacing Demolitionist at the task).
