Terrors should stay in the Weapon depot and defend; since you spawn real close to the Counter-Terrorists, you should give them a bit of a chance you gear up.
A good place to stand is behind the back door with a weapon that will shoot threw a wall. If a Counter-Terrorist opens it fire away, they'll never know what hit them.
Next there is the vent, go in, climb the ladder and camp at the top. If you hear someone throw a flash bang, back up a bit because you may get hit if you're looking down at the vent below. Also try crawling back to the end of the vent and stand on the vent cover with a riffle, when you see a Counter-Terrorist pop his head up, blow it off. =]
The next place to defend is in the hostage room It may sound boring, but that's where all the Counter-Terrorists are heading for so by the time they get there, they'll probably (if you have a good defense) be half dead and you'll be the last person they'll want to see.
Another good spot is under the bridge, behind the fence. Stand there with a riffle and snipe threw the fence, most people wont notice you.
Watch the vent by the hostages, if you see a Counter-Terrorist in there, shoot out the cover and throw a HE Grenade up into it.
And finally there's by the big door, if you see a Counter-Terrorist run in, take a few shots, don't jump down and run after him, sniping Counter-Terrorists will probably kill you then.
Offence:
Counter-Terrorists should rush, don't wait around because most Terrors rush and they're not far away. The best thing to do is download RzE's Bag o aliases, and use them so you don't have to wait to buy weapons or ammo.
Run to the weapon depot and go up one of the ladders, go across the roof and throw a flash bang into the vent, then climb in. Watch the vent opening in front of you for terrors and the ladder going up half way threw, if you see one at the ladder throw a HE Grenade up, if there's one in front of you shoot him (duh).
Or you could go up onto the bridge and snipe, but most players call this camping so don't do it all the time.
Go up onto the bridge, go all the way to the end and jump off onto the ledge, go along the ledge until you're right next to the Weapon depot. And watch for terrors rushing out.
Counter-Terrorists should use the spot behind then fence too; it's a great sniping spot.
Sniping: Terrorist
There are lots of places to snipe in the Weapon depot, as long as you know where to look. ·
The pile of bins by the back door gives you great cover from two sides if you're coving the big door.
The pile of crates in the corner by the back door is good for covering the back door, but you're an east target for Counter-Terrorist snipers there.
If you get into the vent going towards the hostage room, you can stand on the vent cover and snipe from there, tell you're team though because they may shoot the cover out from under you thinking you're a Counter-Terrorist.
Sniping: Counter-Terrorist
Counter-Terrorists have by far the best sniping spots ·
Climb up on the roof of the building where you spawn, you'll be able to view most of the map and it's great for backing up your team.
The bridge is good from backup too; just don't sit there the whole round.
Use the area behind the fence! ·
If you go up onto the roof of the weapons depot and stand here you'll have a good view of most of the map too.
Dos and Don'ts
Here's a list on thinks to do and not do while playing Assault.
Don't:
Camp in the back of the truck, it's a death trap.
Jump and the end of the vent if you're a terror.
Snipe from the dark area by the your spawn if you're a Counter-Terrorist.
Rush if you're terror, this map is too small for that.
Camp on any roofs or the bridge if you're a Counter-Terrorist.
Don't try to be a hero.
Do:
Defend the hostages if you're a Terror.
Rescue the hostages if you're a Counter-Terrorist.
Stay with your team.
