Commander Shepard is the default character you control in Mass Effect 2, and there is a vast character customisation menu found at the outset of the game that allows you to shape your own character from scratch. Choosing either a male or female, you can modify appearance, abilities and even military background depending on your preferences as a player.
There are a number of classes to choose from, each of which features their own special attributes. For example, Soldier class is the most skilled with weaponry, so if you want a more action based experience, this is the ideal option to choose.
Dialogue plays a huge part in Mass Effect 2, allowing you to choose from multiple responses when conversing with characters you'll come across in the course of the game. Responses vary, allowing you to appear either diplomatic or aggressive, depending on the path you wish to choose. Be warned though; your tone affects the game's missions and the choices you make, so think about your response before delivering it.
While Mass Effect 2 places an emphasis on story and interaction, it's also an action game at its core, filled with plenty of pulse-pounding missions. Throughout them you'll wield an arsenal of weaponry including machine guns, pistols, grenade launchers and sniper rifles. Each of these can be upgraded with special abilities such as incendiary rounds.
