First off, it should be understood that in Counter-Strike: Source (CS), there are numerous different map types. These types are:
Bomb Map (de). The Terrorist goal in the bomb map is to go to a certain location (marked on the map) and plant an explosive. The explosive is with a timer, so once it can be planted, you need to defend it until detonation.
The counter-terrorist goal on bomb maps is to prevent the terrorists from planting the bomb at all costs. You can do this through the elimination of every one of the terrorists, defusing the planted bomb, or (in some cases) defending the bomb site until time expires.
Hostage Rescue (cs). In hostage rescue maps, the key goal for counter-terrorists is always to rescue hostages captured and held from the Terrorists. You may also win by reducing the terrorist team.
The Terrorist goal is always to simply avoid the counter-terrorists from rescuing the hostages by reduction of them, or maintaining charge of the hostages until time finishes.
Bomb Maps – Counter-Terrorist. Like a counter-terrorist on bomb maps, the best choice (by far) is to get rid of the terrorist team before they’re able to plant the bomb. Defusing the bomb makes you a sitting duck, which is a situation you want to avoid. Maintaining your terrorists seeking to plant the bomb means you’re able to remain on the defensive, giving an advantage.
Bomb Maps – Terrorist. Like a terrorist, your main goal is to completely overrun a bomb site. If you can not take control of a bomb site from the first Half a minute, your team will more than likely lose the round. The most effective technique is to rush everyone on the team aside from Two or three (tops) to a single site. The other few players will work as a distraction in the other site, therefore the counter-terrorists guarding it are not designed in as re-enforcements.
Hostage Maps – Counter-Terrorist. I’ve found the best tactic to be spreading the c’s out and attacking coming from all angles. Coordinate a simultaneous attack if possible, but make certain nobody just “runs in, guns blazing,” because that technique almost guarantees death in a hostage map.
If one side with the attack is able to punch through and get inside area under Terrorist control, all of those other team should turn to that area so that you can assist the attack.
