Seriously, look at what you're arguing about, a scored based shop.
Racerboy you know how Furdle and Pass work towards criticism, yet you had to come in there and do your show, "omg shop sux" "thsi gam sux" "forget of pass shop sux".
Both sides are wrong here, shop systems are indeed flawed if you put value weapons according to their firepower, rate of fire, etc.
Racerboy stop pulling a Bushido you don't know how to do it.
Ok Furdle, here's what you should do man, make all the weapons unlocked, but you can unlock stuff for them like a different color, a new skin, a diff model that does the absolute same thing, make the unlocks entirely visual (you can have some differences if ya'd like).
Here's an example:
laser pistol - starter
laser pistol with blue projectiles - 200
laser pistol with blue projectiles + scope - 300
laser pistol with green projectiles - 200
laser pistol with green projectiles + scope - 300
laser pistol with red projectiles + scope - 300
golden laser pistol with purple projectiles + scope - 500
