Hitting a Lurker or a member of the Pack with just one shot is a guaranteed kill, and coupled with stasis it is extremely effective against the Puker and Spitter, capable of dispatching either before the effects of stasis wear off. In Multiplayer, the Seeker Rifle is extremely effective, although difficult to wield.

In addition, you only need to invest 10 Power Nodes (for all Alt Fire nodes) to max out the damage if you only plan on using the zoomed mode. Because of this, if no points are invested in the alt fire, it can be detrimental to use the zoom due to reduced visibility and potentially reduced damage depending on the number of damage nodes invested in. In Dead Space 2, the damage and alt fire (zoomed) damage are separately upgraded (damage from 50 to 70, alt fire from 50 to 100).If adequately invested in, a Seeker Rifle can end the final battle in less than 30 seconds without the Pack ever appearing. Zoom in and take two shots (three shots on Hardcore), and it becomes vulnerable. A fully upgraded Seeker Rifle is one of the best things you can use against the final boss, second to only the Contact Beam in terms of effectiveness.A Seeker Rifle with fully upgraded damage (100 pts), will kill any early enemies in a single shot to the body, even on Zealot difficulty.You can easily pop off its head or take out one of its legs. Use it against a slow enemy such as a Pregnant.

Using it at close range isn't a good idea, but if you're good with semi-automatic rifles, it can be a very effective, almost-always one-hit kill against most enemies, even with body shots.
