Apart from the fact that bots usually behave in strange ways (see Bots or Humans? ), you can say it watching the score table: bots have ping 0, and usually (but not in all servers) a gun barrel in the first table column (named “Skill”). The number of bullets in the barrel (from 1 to 6) shows how much skilled the bot is.

For some weapons, definitely yes.
Have a look at the equipment in SG Manual, where “Primary Fire” means shooting with left mouse button and “Secondary Fire” with the right one.

Pistols: Remington 1858 Model, Smith & Wesson Schofield, Colt Peacemaker:
With secondary fire you shoot faster (though less accurate than with primary fire) leaving your opponent no time to counteract.

Shotguns: Remington 12 Gauge, Sawed-Off Shotgun:
Secondary fire = double shot (both barrels).

Bowie knife:
If you have more than one knife you can switch between slashing and throwing mode with the secondary fire button.

Dynamite Stick, Molotov Cocktail:
Secondary fire is used to light them.

Gatling Gun
Secondary fire disassembles the Gatling gun so you can carry it with you.

A handicap is something that penalizes you: you make less damage to your opponents while you become more vulnerable. It’s only useful to good players that want play at the same level of noobs.

To remove your handicap, type: ESC –> Player –> Handicap … and select “NONE”.

In SpecialBude you can climb every vertical surface. When you are close to the surface, just jump and climb. It’s fun!

Default key (US keyboard layout) is the tilde character (~). The same key is used to close it.

Generally speaking, it’s the key placed under the ESC one.

With some systems and keyboard layouts, however, tilde is obtained by a combination of AltGr + the key at left of Backspace.

If none of these solutions works press Shift+Escape at the same time, this will bring down the console on any system.
