Slow-mo Deathmatch – F.E.A.R. Combat
Before playing F.E.A.R. Combat, I never thought slow-motion was possible in a multiplayer game. This game changed that misconception completely, by the means of such an awesome slow-motion deathmatch mode that I got hooked to the game instantly. They way they implemented this is via the use of an in-game item – the injection.
Whoever holds the item for a certain amount of time gains the ability to set time in slow-motion for everyone but himself. This gives him an incredible advantage, allowing him to plant headshots with ease while his enemies struggle to move. Although this seems game-breaking, the amazing thing was the way they balanced it out – the slow motion doesn’t last long enough for the yielder to run around constantly in slow-motion; only a few seconds. This ensures that everyone would pounce on the yielder once the slow-mo was over, so that the injection would be passed around quite a bit.
