How to unlock the Swift and Deadly achievement in Turok - Definitive Guide
* I didn't realize until after I got it that you could get this achievement on beetles. I recommend that you play through the game before trying this, and get it on beetles. I couldn't remember what levels had beetles after I beat it, so I got it this way.
For this achievement you must kill 3 enemies with one attack of the knife. What you will want to do is lure 3 enemies close together in front of you then charge at them and attack. This works well on the beetle's which normally come in numbers an are a one-hit kill. You can gain this achievement on the first level just after the first save point.
Once you reach your first save point as seen below, make a game save then continue on by following the path directly opposite, as soon as you cross the wooden bridge you will reach an area with three men and some lava, what you will want to do is lure all three people close together then rush them and hit then all with the same blow of the knife, the achievement should unlock. if you miss one or take a couple of attacks then just reload your save and try again.
Note: The guy in the middle has grenades so don't stand too close to him until your ready or he'll kill himself.
The first save point:
