Hardsuit
The Hardsuit has a minigun that is particularly effective in up-close encounters while the railgun is more accurate long-distance.
Be weary of flamethrowers as they will get burn out of your suit and somebody else can take it once it cools down. Also keep an eye out for stingers as a Hardsuit can only take two hits from those (unless it's in Combat mode). The Hardsuits can 'Dash' or 'charge' forward which is often more efficient that attempting to aim it's big heavy guns when the enemy is strafing in front of you.
