Comparing Mass Drivers in Infinite Space and BattleTech: Similarities and Differences

Comparing Mass Drivers in Infinite Space and BattleTech: Similarities and Differences

In the Infinite Space trilogy, a Mass Driver is a capital ship-mounted weapon that functions like a hybrid of a Micro-Meteorite Gun and Gauss Cannon. The resulting weapon spits out a cluster of molten metal fragments in a spread pattern over moderate ranges. However, the Tan Ru Dominator, is the only capital ship that carries at least one of this weapon in their default loadout, and even then, it faces backwards, to deter pursuers. There's a good reason for this, though: the Mass Driver's wide spread pattern makes it highly inaccurate beyond point-blank range (especially against unshielded ship hulls), which limits its usefulness. As such, it is best combined with other weapons (preferably longer-ranged ones) if you want to get the most out of it. Within its short effective range, however, it can be very devastating, especially when used in conjunction with a targeting computer of some sort.

Above, from top: Mass Drivers in Sea of Stars are not very accurate at longer ranges, but are very effective up close.

The range profile of the Mass Driver makes it well suited to sneak attacks using cloaking devices: stick it on a cloaked capital ship (preferably a fast one), get it close enough to a target, then have it decloak and attack - it will chew up its victim in seconds.

Mass Drivers in BattleTech, however, are nothing like the ones in Sea of Stars; they are instead massively scaled-up versions of Gauss Rifles that have not only been used by civilian mining and manufacturing companies, but also as capital ship and space station-mounted military weapons. Due to their extreme mass, size, cost, inaccuracy, and destructive potential, however, their use is highly restricted, even in the most desperate circumstances imaginable. Instead, the Clan Hyper-Assault Gauss Rifle (and its Inner Sphere equivalent, the Silver Bullet Gauss Rifle) serve as the BattleMech-sized equivalents of Sea of Stars' Mass Driver. Both weapons fire a cluster of small-caliber slugs instead of a single larger-caliber shell, thus increasing the damage done and, in the case of HAGs, the amount of heat generated.

The Hyper-Assault Gauss Rifle and Silver Bullet Gauss Rifle are recent additions to the growing arsenal of weapons in MWO - both were only introduced in the past few years - but they are among the most powerful ballistic weapons available. Clan HAGs come in three sizes (20, 30, and 40), allowing you to choose a type depending on the amount of unused mass and critical slots available. Inner Sphere SBGs, on the other hand, are not yet counted towards the heat scale limit in the same way that regular Gauss Rifles and PPCs are, while requiring the same amount of mass and critical slots as a standard Gauss Rifle or Clan HAG does. Regardless, the tight spread of HAGs and SBGs makes them quite accurate at long range, although both of them are just as effective at closer ranges.

In short, the Mass Driver in Sea of Stars is very different from its BattleTech counterpart, but once you learn how, when, and where to use it, it can be just as effective as most other weapons in its price range.
