Little is known about the batarian homeworld of Khar'shan or its inhabitants. As a result, the race is judged by those whom the Hegemony allows to travel beyond its borders: organized crime enforcers, pirate boarding parties, slaver gangs, and gladiatorial combatants.
Batarians are large brawlers that use nets and spiked weapons to capture targets...or to bleed them dry on the battlefield. If an opponent gets too close, a batarian enforcer bludgeons them with spiked armor and enforcement gauntlets.
Enforcement Gauntlets - The Batarian Soldier winds up a powerful punch with an omni-tool gauntlet.
Batarian Soldiers lack a dodge maneuver.
With Ballistic Blades, Batarian Soldiers are lethal at close-quarters, capable of dealing with any enemy, but they are ineffective at range unless using appropriate weapons. Ballistic Blades can be thought of as a shotgun with a cooldown. A build utilizing Ballistic Blades as often as possible should aim for a low cooldown.
Builds utilizing only Blade Armor and Inferno Grenade have no need for low cooldown times unless the player is attempting to reactivate Blade Armor after deactivating it.
Batarians are unable to evade, making them more vulnerable to instant-kill moves.
Note also that while batarians are actually faster than regular humans, they are also less defensible than krogan. They are more vulnerable to staggering attacks like Geth Prime pulses and Geth Hunter shots as a result, but are still more reliable for delivery and drone escorting operations than drell or krogan, having more or less the movement speed of the former, and the similar durability of the latter.
When evolved for Radius, Inferno Grenades can have a massive area of effect. This can be used to quickly kill the weaker enemies in a group, and prime the tougher ones for a devastating Fire Explosion. However, the Batarian cannot detonate these combos by himself.
