Here are the upgrades you've been waiting for:
Upgrade 1: Quad-Blaster
Double your blaster fire, but not your wallet. Only $5 extra.
Upgrade 2: Turbo-Chargr
Get your blaster charged faster, but risk overloading it and turning it into a toaster. Worth it.
Upgrade 3: Splendor-Shield
Protect your blaster from those pesky Splendor-Snipers. Only works on Wednesdays.
