Lure Obscurity players to doorways and small spaces to make them easier to hit.
Always have a fallback point or plan of action (Clays, retreat position etc).
Corners and doorways are good points to release a knife attack on Obscurity players when you don't have a chance to reload.
Lasers are a sure way to attract a Push Nade, so try to place your explosives away from lasers.
Don't spray and pray, be precise with your shots. You won't be in the game too long if you TK, and you will want to use your ammo wisely.
Use your ears. Many Obscurity players are rush crazy, which means they are not capable of masking their sound via firemodes & stealthy movement, giving you time to prepare an unhealthy dose of lead to send in the right direction.
Combine x3 Frag perk with Incendiary Nade perk to get x3 Inc Nades.
Battle Hardened reduces flash blindness duration greatly, along with the blood spatter reduction.
Flashbangs will only blind you if you are looking at them, so turn your back to them & you will only suffer momentary deafness.
Blood spatter is directional, so if your left side of screen gets spattered, it's best you look that direction and take out that Obscurity.
Grenade Launcher rounds are now set to a fuse. Giving you more options with the weapon and making you look less like a noobtuber. Bounce those nades around corners, off walls etc.
Smoke grenade colour is dependent on which squad you are in.
Squads allow players to work in small/coordinated 4 person fireteams and track each others movement.
While Obscurity, if you see a marine with an Obscurity symbol above his head, than it is a possessed player, so don't go and kill him unless you want a TK.
Don't tag other players on purpose unless you want to die.
Obscurity players can drop off a wall they are stuck on by holding "use key" if they do not want to leap off.
Obscurity players can possess through walls, so it's best to move lots or not camp near a wall that has access on the other side.
Taunting is a good way to scare marine players, but beware that it will give your location away.
Tornado Firemode works particularly well on bodies.
Tracking Firemode allows all Obscurity players to see your target, so if you want the kill you better move quick.
Hunter perk works particularly well for people with shotguns who tag lots, but never seem to drop the enemy.
Push nades are a great way to take a marine out who is near explosives or up high.
Hearing stab sounds, glimpsing flashes of obscurity, but cannot hear any near you. Don't panic you are probably hallucinating. It' s best to check around carefully as it's likely an Obscurity is near by watching your reaction.
You can toggle Obscurity vision on and off during spectate via the "grenade key"
Be aware of teammates close to you when camping. They could be replaced by an Obscurity at the blink of an eye so make sure you know where they are.
If you hear the phrase "Melon Ban" it's best to behave, as those special enough receive a Mod Wide Ban (not server wide). Death by melons every spawn. Respect server rules!
Obscurity do not need to wait for leap recharge if they are leaping from a 'stuck-to-wall' position, so fulfill those Spiderman fantasies.
A swap-drop-death here and there is ok, but don't do it too much otherwise you are asking for a ban.
Try using Pull Firemode on an enemy below you when stuck to the roof. if timed right you can pull off a pretty nifty knife kill.
Headstabs are the Obscurity version of a Flashbang, so use this to your advantage. The resulting blood spatter is blinding to all.
The Obscurity can become the ultimate stealth killing machine if used correctly.
Hustle is extremely effective when working in a squad. Your group will be able to move around the map with ease if one person has it.
Static Firemode is a great way to stir things up and mask your presence.
If everyone knows you have possessed someone you can always ditch the body by holding the "use key" and take advantage of the marines being extra suspicious of each other.
Using wounded players as bait is very effective, but beware if they have the medic perk, as they will run the first chance they get.
Be wary of cries of pain from gutted marines, it will help you know when your medic services are required and also let you know that an Obscurity is on the hunt nearby.
You stand more chance running than successfully reloading while under Obscurity pursuit. This is where a good fallback plan should come into action.
Using yourself as bait can be extremely effective when combined with a "tweaked" car, just be careful of incoming Push Nades.
