Civilization IV is a 2005 turn-based strategy developed by Firaxis, and created by Sid Meier. The premise of the game is starting with a band of settlers in the year 4000 B.C. and creating a civilization to stand the test of time. Once the player enters the Renaissance Era and beyond they have the ability to create units armed with many firearms. While the graphics are low quality (Which makes some guns difficult to I.D.), many guns are very intricate in their design and easily recognizable.
The following weapons are seen in the video game Civilization IV (and expansion packs):
Single Action Army
If the player is granted a Great General in the Industrial Age and beyond, the Unit is seen wielding a blocky looking Single Action Army. The look of the General appears to be based off of George S. Patton, so the use of a Colt SAA is fitting.
