Rage
The best way to fight enemies in Marvel Nemesis is to fight in Rage mode. There is a bar that says how much rage a player has. Every time you do damage to an enemy, the rage bar increases, but every time you are damaged, the rage bar goes down. Once the rage bar is full, press the power button to release the rage, and for a certain amount of time, all the enemies will slow down while you continue playing at normal speed. Your attacks will be more powerful during Rage mode.
Surroundings
As you progress through Marvel Nemesis, keep an eye on the surroundings. There are often items on the screen that can be thrown at enemies, such as barrels, rocks and even cars. Throwing these items at enemies can be very valuable because you can avoid danger by attacking an enemy from a long distance.
Bosses
There are a few instances when a boss fight will take place close to a bridge or cliff. If you are having a difficult time killing a boss, then an easier option is to simply throw the boss off the bridge or cliff. If the boss falls off the bridge or cliff, the boss will instantly die. It is also possible to sacrifice yourself when knocking a boss off a bridge or cliff. As long as the boss falls off the screen first, you will win the battle.
Characters
Each character in Marvel Nemesis has different strengths and weaknesses. Probably the best character in Marvel Nemesis is Iron Man. Iron Man's suit allows him to be not only strong but also agile, while most of the other characters are one or the other.
The worst character in Marvel Nemesis is probably Storm because her punches are the weakest out of all the characters. Thing is the strongest character if you want to just smash through the game. If speed is more your style, then Daredevil is swift, and he also has more deadly hand-to-hand skills than the other swift characters in Marvel Nemesis.
