"Half-Life: Opposing Force"-released in 1999-is the first single add-on to the Genre size "Half Life." The secret, huge Black Mesa research Station. An Energy Experiment has gone thoroughly wrong, opening a Portal to another World. Strange, aggressive Aliens flock to our World, attacking everything that runs their Way. In order to master the Supremacy, heavily armed Military is also activated ... As Corporal Adrian Shepard, we find ourselves in a Troop Transport Helicopter. After this is shot down right at the Beginning, it is important to survive alone, find Weapons and assert ourselves against Security Systems. Again, the Levels are extremely varied, shooter passages alternate with switch or jump passages. We are usually on the road in Black Mesa, but through Portals we also get to the alien world. We are mostly on our own, but in a few Moments we should use a new Mechanic, which is to give rudimentary orders to other Soldiers. At the same time, "Opposing Force" never becomes a real tactical shooter, over a "schneidbrenn me the Door open" it hardly goes out; A nice Addition it is nonetheless. A Lot of new Weapons are coming into the Arsenal. The Sniper rifle and the Heavy Machine gun are certainly particularly obvious. Instead of a Crowbar, we now have a Pipe Pliers and a fancy Knife. New, very cool Alien Weapons are also on the Grid, including a living Alien that we first have to feed so it shoots corrosive Liquid. Otherwise, the Game Mechanics of the First-person shooter work as smoothly and smoothly as in the Original. The Pacing is excellent, the Puzzles are interesting, the Degree of difficulty has been attracted, but this, mindful that you Usually have already pulled the Original before and thus has Practice with the Mechanics, feels just right. Even the Irony has not lost "Opposing Force" (incidentally like Half-life or Blue-shift/blue shift also a physical Term). For Example, you'll find a Mural of Gordon Freeman with the Caption "Employee of the Month" or to defeat a giant Worm, a Gearbox and a Valve must be activated. Graphics and Sound remain essentially on the (very good) stand of the Main Game at the time. That one witnesses the Events of the Original From a different Perspective, so "Opposing Force" plays practically parallel to "Half Life," is a very wise decision, which contributes significantly to Immersion, because Somewhere Gordon Freeman is now running through Black Mesa and fighting His own Struggle. Maybe as Adrian Shephard we'll even walk along the Way ...
