I have recently been granted the go-ahead to look into making a Bionic Dues expansion, and my current idea is the following: A new building with powerful, but buggy, weapons that you can use. In the building, my plan would be to have it be a kind of Super Lion's Den, so there would be a massive amount of enemies, but killing them wouldn't change the final battle.
So how does that sound to everyone here? Also, feel free to post your bugs so I can take a look at those at the same time.
EDIT: Let me just stress that THIS DOES NOT MEAN A BIONIC DUES EXPANSION WILL HAPPEN, only that we are looking into making one. There are quite a lot of factors that would stop the expansion from coming out, first and foremost being a bad money-to-fun ratio, and second it just not being fun in some way.
