LEADING YOUR TARGET
All but a few weapons in the game fire projectiles that take time to reach their target. That means you have to fire not where your enemy currently is, but where you think he will be when the projectile hits. This is where all the running and jumping around comes into play. If your enemy is running in a circle, fire a bit in front of him. If your enemy is airborne, do NOT fire at him unless you’re using an instant hit weapon (and even then try to avoid it). Instead, try to see where he will land and send a few rockets/bombs to greet him. If your enemy is dodge-jumping, chances are you won’t be able to lead him, so try to keep him in sight and shoot when he lands. Leading target is even more important in vehicles, since most have slow moving projectiles. Even when your vehicles has a fire-and-forget homing weapon it still pays to lead target a bit, since most of what you’ll be aiming at will be very fast.
Even though both sniper rifles in the game are instant hit weapons, it still pays to lead target with them. Even if your reaction time is perfect, it still takes some time to process the thought, pull the trigger and draw the animation, and it only takes the enemy a couple of frames to get out of the way if he is running. So lead target just a bit. Aim for the head ONLY if you’re very good, or if you’re aiming at a stationary target. Headshots are sweet, but you can still score hits without them, so aim for the torso. It’s big, it’s round, and a shot there often kills players who are low on health. Also, when sniping, remember your shoes are not nailed to the ground. If you notice someone shooting at you move to the side or hide behind something without un-zooming. This is even more important when fighting another sniper, since he will have as good a chance to kill you as you will have to kill him. Strafe and constantly change directions while your gun is reloading. A good strategy is strafe until he shoots, then stop to get a better aim while his gun is reloading. Additionally, the Hellbender has a beefy sniper cannon on its back, but more on that later.
KNOWING YOUR WEAPONS
Learn what each weapon does and what it is good for. Then learn what each of the fire mode of each weapon is good for. We’re talking situation, range, accuracy, specific characteristics. These are weapon specific, so I’ll get into detail later. Another thing to do is REMEMBER what weapons you have. Don’t hog “the most powerful weapon” you have if it’s wrong for the circumstances. Recall (or look at) what weapons you have and switch to one that is more appropriate. Keep in mind that not all weapons are displayed in the HUD inventory, due to the lack of space. Also, keep in mind that there is no “most powerful weapon” in this game (with the possible exception of Superweapons). If you think the Rocket Launcher is the best, try using in crammed spaces. If you think the Flak Cannon rules, try using it at long range. But more on that later. Knowing your weapons is even more important when it comes to vehicles (which are just weapons with health instead of ammo). If you can’t drive a certain vehicle, leave it to someone else. Only take vehicles you’re not familiar with if there is no-one else around. Vehicles are very valuable and must be put to good use, lest the team loses. Each vehicle has its own characteristics, things it can easily kill and things that can easily kill it, so learn those and try to tag along with vehicles that can protect you. More details later. Additionally, some vehicles require people on foot (yes, people on foot) to protect them.
ANTICIPATING ENEMY MOVES AND LEARNING THE MAP
This is key, especially in Death Match. Don’t chase an enemy down a hall while he’s plastering you with flak grenades. Stop, think where this hall leads and intercept him. This catches 9 out of 10 people unprepared. If your enemy is trying to hide behind a pillar, don’t follow him around in a merry-go-round. Either shoot on the other side of the pillar, or circle the other way and outflank him. People love to pick up weapons. Therefore, it’s a good idea to just fire a rocket or bomb at heavy weapon locations every time you pass by, just in case. Also, in a firefight, people will want to pick up weapons, so sometimes it’s a good idea to fire your rockets/bombs at a pickup, rather than leading target. That works especially well with Shield Packs. Another good idea is, when you are being chased, turn a corner and wait a couple of seconds. If your pursuer comes after you, feed him some Flak. If he doesn’t, Dodge-Jump back around the corner and give chase. Know how to get to Nodes quickly and learn to navigate on the radar map (on Onslaught). Also, try to tell where an enemy is heading and teleport around the map to intercept him, rather than chasing him, since once he attacks a node, you can no-longer teleport there. If the enemy is attacking your node, there’s a good chance you can sneak up on him for maximal damage. Don’t open pointless fire from a mile away, only to be blasted by a Tank cannon.
No, using Superweapons is NOT cheap, it’s a tactical advantage. In fact, using Superweapons becomes a form of art with friendly fire on, in that you want to kill the enemy without incinerating your own team. In certain situations (especially against a Leviathan) you will actually need Superweapons. Learn where they spawn and how long they take to respawn. Learn where and when to use them. Different Superweapons are good for different things, but they are all good for more than just scoring frags. You could vaporize the entire defending team (and yourself if need be), thus allowing your team-mates to capture the flag/hold the point/capture the node/whatever. Inversely, you could kill an enemy strike force that has stolen your flag if your whole team just got nailed. Of course, you must always be careful that you don’t do so much collateral damage that it makes your act treason. If there are a lot of friendly vehicles around, then it’s probably not a good idea to fire, since they may just hold their ground. There are other uses of Superweapons, but I’ll explain them with each weapon.
