To begin with, it must be understood that in Counter-Strike: Source (CS), there are many different map types. These kinds are:
Bomb Map (de)
The Terrorist goal in a bomb map is to run to a certain location (marked on your own map) and plant an explosive. The explosive is on a timer, so once it is planted, you need to defend it until detonation.
The counter-terrorist goal on bomb maps is to stop the terrorists from planting the bomb at all costs. This can be achieved by eliminating most of the terrorists, defusing the planted bomb, or (in some cases) defending the bomb site until time runs out.
Hostage Rescue (cs)
In hostage rescue maps, the principal goal for counter-terrorists is always to rescue hostages captured and held by the Terrorists. You can even win by eliminating the terrorist team.
The Terrorist goal is always to simply stop the counter-terrorists from rescuing the hostages by eliminating them, or maintaining control of the hostages until time runs out.
Bomb Maps – Counter-Terrorist
As a counter-terrorist on bomb maps, your absolute best bet (by far) is to get rid of the terrorist team before they could plant the bomb. Defusing the bomb makes you a sitting duck, and this can be a situation you want to avoid. Keeping the terrorists trying to plant the bomb means you can stay on the defensive, gives you an advantage.
Bomb Maps – Terrorist
As an enemy, your only goal is to totally overrun a bomb site. If you can not seize control of a bomb site within the first 30 seconds, your team will likely lose the round. The best strategy is always to rush everyone on a team with the exception of 2 or 3 (tops) to just one site. One other few players will behave as a distraction at the other site, therefore the counter-terrorists guarding it don’t come in as re-enforcements.
Hostage Maps – Counter-Terrorist
I have found the most effective strategy to be spreading the team out and attacking from all angles. Coordinate a simultaneous attack if possible, but be certain nobody just “runs in, guns blazing,” because that technique almost guarantees death in a hostage map.
If one side of the attack manages to punch through and get inside the area under Terrorist control, the remaining portion of the team should go on to that area to be able to assist the attack.
Hostage Maps – Counter-Terrorist
As terrorist, your only strategy here should be to sit and wait. Your goal is to allow them to come to you. Sit, Wait, and SHOOT!
Shoot a round from your pistol at the beginning of the match. Once you think (or hear) an enemy nearby, switch to your pistol, press reload, and quickly switch back to your primary rifle. Most enemies will jump out and attack if they hear the reload sound, because they think you are defenseless.
This has turned into a staple of counter-strike in the last years, however many players do not exactly understand it. If you are in a firefight at range, you can strafe-shoot to maintain accuracy but nonetheless get yourself an arduous target.
The way in which strafe-shooting is completed is by pressing (or tapping) the strafe key to truly get your player moving and releasing it really as you commence to fire. Your player will continue to go for another step, your shots is going to be accurate.
The AWP No-Scope
Many individuals experienced problems with this particular, and it is really so simple. A No-Scope shot is when you shoot an opponent with a sniper rifle without utilizing the scope. For many sniper rifles, the cross-hairs have already been removed if you are not utilizing the scope, and the weapons are extremely inaccurate. This is done intentionally to force visitors to use the scopes on sniper rifles. The issue with the scope is that it is difficult to make short-range shots, and your player moves very slowly while looking through it, so you feel an easy target. The clear answer to this is the No-Scope shot.
The No-Scope is completed simply by pressing the proper and left mouse buttons at once while your intended target can be as near to the center of one’s aiming point that you can (you need to estimate this). The scope will appear for a tiny fraction of an additional, and your shot is going to be accurate.
You will notice after playing Counter-Strike for quite a while that a lot of players follow very predictable patterns. Ammunition is expendable, and any of the rifles (AK-47, M4, etc.) will penetrate through about the first 3 inches of a corner. When approaching corners that likely have opponents on the other side, shoot the corner. You will often hit your enemies before they see you.
