Horsepower

Horsepower (hp) is a unit of measurement of power (the rate at which work is done). There are many different standards and types of horsepower. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied between geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on January 1, 2010, the use of horsepower in the EU is permitted only as a supplementary unit.

Team Fortress Classic

Team Fortress Classic is a team-based online multiplayer first-person shooter video game developed and released by Valve Corporation in 1999. Based on the 1996 Quake modification Team Fortress, the title was ported to Valve's GoldSrc engine as a way of promoting Half-Life's software development kit.

Matches in Team Fortress Classic pit two teams against each other, with each team member having access to nine distinct classes. Competition takes place in a variety of scenarios, usually capture the flag, VIP protection, or territorial control. Since its release, the game has undergone significant upgrades to player models and game modes.

Gameplay

Matches in Team Fortress Classic feature two teams, one red and one blue, and nine playable character classes. Each character class has a set of weapons and abilities unique to that class. This differentiation between classes makes for rock-paper-scissors-esque gameplay that requires teammates to work together in order to effectively achieve objectives. The class-system also encourages players to vary their selection of classes and utilize certain classes in conjunction with one another to gain the advantage.

In Team Fortress 2, players join one of two teams comprising nine character classes, battling in a variety of game modes including capture the flag and king of the hill. The development is led by John Cook and Robin Walker, creators of the original Team Fortress. Announced in 1998, the game once had more realistic, militaristic visuals and gameplay, but this changed over the protracted nine-year development. After Valve released no information for six years, Team Fortress 2 regularly featured in Wired News' annual vaporware list among other ignominies. The finished Team Fortress 2 has cartoon-like visuals influenced by the art of J. C. Leyendecker, Dean Cornwell and Norman Rockwell and is powered by Valve's Source engine.
