—The Quake II Manual
The Railgun, or "RG", fires an extremely powerful slug at its target. It has immense power, being able to kill an unarmored player in one shot. However, it has a noticeable pause between shots, so you'll be very vulnerable between shots. Nonetheless, the Railgun can inflict serious damage. The Railgun, due to its slugs' high speed and excellent accuracy, is arguably the best sniper in the game.
- The Railgun is the second most-powerful and sonorous weapon in the game, delivering 150 damage points per shot. It can destroy a Tank within five shots, and others with less. Because of its power, it's advised to stock up on ammo for larger (and slower) enemies. Ammo is somewhat common, so it shouldn't be a problem unless the player makes it their weapon of choice against all Enemies.
- Though the Railgun delivers a powerful punch, the user needs to be accurate or they will find themselves misfiring all the time, however, this should not be a problem if your enemy's slow.
- In single player The Railgun delivers 300 damage if the target is unaware of the player. In this case a single shot will kill Gunners, Parasites, Iron Maidens, Berserkers, Technicians, Mutants, Medics, Brains and Icari. The Gladiator will fall in two shots. Combined with the Quad Damage the railgun will gib the Tank and even kill the Tank Commander in one shot if they have not spotted the player.
- As stated in the manual, the slugs penetrate an infinite amount of enemies until hitting a wall, so try lining up enemies if possible. This saves ammo as well.
- The Railgun is a good pick against bosses. 10 shots will take down a Super Tank, the Hornet dies in 14, and lastly, the Jorg and the Makron fall to about 20 slugs.
- The Railgun is the most useful weapon in MP. As stated earlier, it can take out an unarmored player in one shot. Being able to predict where a player will be can turn you into an almost-unstoppable wrecking machine. Even if your predicting skills aren't really good, you should be able to get a few kills with it before you die.
- The Railgun is the perfect weapon against campers, Make sure they don't see you ortherwise they may run away and hide.
- When fighting against somebody that has a RG, you must move in an erratic pattern and be able to mix up your routine with different moves. If you stick with one pattern, they'll figure it out and tear you apart. Don't forget that you have a chance to attack without retaliation between their shots, so remember to shoot them as soon as they've fired. Using a weapon like the Hyperblaster in short bursts is a good deterrent against a Railgun user, as they'll frequently move to dodge each barrage, in turn ruining their aim.
