RTL Biathlon 2007 is a simulation of the winter biathlon sport, combining
two disciplines: cross-country skiing and rifle shooting. The competition
takes place on nine skiing areas. The skier moves forward by keeping a button
pressed, which consumes energy. The amount of energy varies in different
sections of the level (more when going downhill, less when going up), and
releasing the button allows for some generation, while the skier will move
slower. When overexerting the athlete, the energy levels move into orange and
red, and a large amount of stamina is consumed. Other techniques include
gliding (crouching when going downhill) and sprinting in certain areas. The
shooting sections are shown from a first-person perspective. The accuracy
depends on the remaining stamina. Players can also hold their breath to steady
the rifle, but this depletes the stamina levels further.

The different game modes include Practice, Career and Multiplayer. By
competing in different leagues, players earn experience points that eventually
open up power points to be distributed over a number of skills. At the start
of the game, players can choose a preset skier or create a custom one,
determining the name, outfit and skill level. Multiplayer is available for up
to four players (hot seat mode) or two in split-screen.
