Large Kills
To take out large amounts of enemies on the following levels just follow the instructions. (Note that these are only a few instances of "Large Kills." Experiment to find more!)

Stage 1, Scene 1
A little bit after you get to the coblestone street you should see an oil tanker in the background, blast it and most of the baddies on-screen will will get blown away.

Stage 2, Scene 1
At one point you should see a platform with a metal strip, balst the strip and most if, not all, the enemies will be taken out.

Stage 2, Scene 2
Shoot the red fuel barrels in the room to blow the enemies away.

Dodging
To dodge a shot quickly duck when you see a red circle appear. This is very tricky, but with practice it can help a whole lot

Extra lives
Shoot 20 people in a row in easy mode or 30 in a row in normal mode to receive an extra life.

When you enter the boat and are in the room before the next stage, there is a vase. Next to that is a glass. If you shoot the glass you will get an extra life.

Repel the knife
On Kantaris' Yacht, towards the end of Area 3, you will fight enemies in the kitchen and encounter the somewhat crazy chef. This chef is a toned down version of Sherudo from the first Time Crisis (with a more basic style). One ability that you can use against the chef (but could not use against Sherudo), is that you can fire at a flying knife in mid-air to actually stop it and receive a bonus. However, it is extremely hard to connect with in the heat of battle, and for some players, may be impossible to accomplish.

Boss area at the end of the game: Extra life
When the "toy" appears and is side on, shoot repeatedly at the spikes at the front of it. You will eventually get another life.

Avoid losing a life
Duck during red bullets. Those bullets will hit you and take away a life.

Know when you will lose
Under the easy difficulty setting, the game ends at Rio Oro. However, under the normal difficulty setting you will get the full mission, including the Titanium Robots and a Wild Dog who seems to be struggling to keep up. However, do not let this fool you. The battle against the Wild Dog will be a shock for normal standard Time Crisis and Time Crisis 2 players. For some, it will be all too easy run out of time during the final point. Skilled players should have no problem avoiding the Wild Dog's still-intact high powered gun arm (which is now very accurate). However, the last action point poses problems concerning time. If you win the fight for the first time, you will most often find that the clock nearly runs out. Here is how the game reveals if you are going make it or not. If during the near-closing seconds of the fight, you see two Wild Dogs appear at once (which are actually two disguised Robot Ninjas), this means you are either about to run out of time, or you will definitely run out and lose. If the two Robot Ninjas are not seen, it means that you have a chance to finish. Once you know they have not appeared, prepare to shoot Wild Dog rapidly as he will advance closer towards you, while rapidly firing the weapon. This is to scare you into hiding and wasting time, when in fact no bullets will actually hit you on-target here. Simply focus on firing rapidly. If you hear Wild Dog cry in agony, you have defeated him.

Glitch: Wrong gun
When you kill a terrorist with a Rocket Launcher or a Machine Gun, they will drop pistols instead of the weapons they held.
