Since all the weapons in L4D are fairly generic, useful, and needed, I'd really like bloko-fied versions of them:
- Auto Shotgun (and I mean an auto shotgun that actually LOOKS like an auto shotgun, not some square with a cylinder attached)
- Hunting Rifle (Faster firing than the Sniper Rifle, does less damage)
- Assault Rifle (Basically an M16 or M4A1, but with no specific name, more damage per bullet than M4, and no different functions other than working with ammo)
- Molotov roostertail (Throws like Spear, disappears from inventory when thrown, when it hits something it lights the ground directly below with (preferably) spreading fire which does damage over time and burns all players caught in the flames)
- Pipe Bomb (Works like HE-Grenade, but instead of just bouncing and blowing up, attracts adjacent bots, takes longer to explode, and has a beeping sound plus flashing red light - Like the L4D pipe bomb, duh.

)
And it'd be great if the guns worked with the ammo system, and had a lot of ammo - 100+ bullets, since ammo runs out extremely quickly when you don't have much.
These weapons would make fine additions to Blockland, IMO. Any one of these will be appreciated.
