Machine Gun :
Level 1 : A good firing rate gun but with less power than the lancer.
Level 2 : Higher firing rate (a bit stronger).
Level 3 : Higher firing rate (a bit stronger) and shield bubbles, wich will blocks enemy shots and will explode when they get three shots from, will appear on the battlefield time to time.
Level 4 : Higher fire rate (Stronger), new type of slow moving bullets but stronger than your main bullets, more shield bubbles and a new type of shield bubble wich will in addition make your main bullets even more powerfull when they get through this "turret" bubble.
Level 5 : Higher fire rate (Stronger), more shield bubbles, more turret bubbles and an upgraded version of turret bubble wich is more powerful and indestructible.
I hope it helped you.
That's a great and simple RPG you've made here. But just a question, have you been inspired with Lovecraft's universe or by the board game "Horror at Arkham" for this game ?
 "Guardians of the Light"){kind=icon}
 "Town of Fears"){kind=icon}
 "Crush The Castle 2 PP"){kind=icon}
 "ButtonHunt 3"){kind=icon}
Glad you like it :) Yes, Arkham Horror was our inspiration.
