How to stay alive and take the fight to the enemy in Mass Effect 2.
The key to survival as a soldier(or any class for that matter) in Mass Effect 2 is effective use of cover. Danger lurks around every corner, so always be mindful of your surroundings and what you can effectively use as potential cover.
Always send your squad mates to scout ahead in an unknown area as they can be quickly healed with medi gel should they fall in battle. As a soldier, your most effective weapon will be your assault rifle, but be mindful of your ammo counter.
Always reload before and after a battle, never during. Be sure to always carry a biotic teammate in your squad to boost your stats and to weaken targets as you pummel them with precision rifle fire and grenades. Also, a note on grenades, they can be the ultimate life saver if used wisely.
Do not use grenades on weak or individual enemies, only use them for heavy enemies that pose a grave risk to you and your squad or several enemies in cover.
So, there you have it. Utilize cover, watch your ammo, take advantage of your squad's varied abilities, and, above all, stay alert. Now take the fight to the enemy soldier, the galaxy is counting on you!
