Thembassy Effect series has, as one might expect, a series of different classes, each with their strengths aNd weaknesses. In someways the combat ranges dictate what will excel, and in some ways the mechanics of the game dictate what will excel. The classes in the series are:

Soldier

Infiltrator

Sentinel

Vanguard

Engineer

Adept

In Mass Effect 1, because of how the game is written, combaor invented classes will excel. Infiltrator and Soldier on the top of this pile, over vanguard and sentinel. The main reason is they have proficiency with sniper rifles. For any other class, these are hard to use. shotguns, which are useful in the final battle by then have sufficient accuracy to be fired reliably from the hip, and really aiming a shotgun? It's an up close and personal weapon. Assault rifles are very useful in the game, taking the place of pistols as the go to weapon of chThe issue is that, they can be hipfired fairly reliably by the end of the game, anautomatic shave a high enough fire rate to compensate. It's on,y early in the game that soldiers have the advantage. In Mass Effect 2 the combat changes make almost any class usable on the lower difficulty settings. Some may claim the Adept shines on insanior tethers say the soldier does. Having played through on insanity, I disagree. The Assault rifle is not as powerful as you might want against the Scions, they will destroy you. Go infiltrator, the invisibility cloak works wonders. In Mass Effect 3, however combat is CQB ranges and enemies are more aggressive. A slow and patient warrior is not the way to go, players need more crowd control. Adepts are great at this, despite their Singularity no longer being an instant kill on husks. The Adept is shorted in the firearms department though, and in a tight spot will be slain without squad assistance. No, in Mass Effect 3, CQB classes like Sentinels, soldiers,vanguards, and to a lesser extent, engineers are best. Their ability to deal with enemies at close range, carry loads of weapons, and survive will win the day.
