Musclemass increases Alex's melee damage twofold and increases the speed at which he strikes. At its base level, a charged attack will turn any human enemy it strikes into bloody chunks; once upgraded, even a glancing blow will cause this. Objects thrown with Musclemass will hit harder, fly further, and move faster than objects thrown at Alex's normal strength; upgrades will augment the distance. Though the game does not explicitly state it, all of Alex's Combat abilities, including Devastators (Tested, need 3 Critical Pain Devastors to destroy a Hive, only needed 2 with Musclemass), will be enhanced by Musclemass. This fact of Musclemass makes it one of the most damaging powers in the game if used with the right abilities.
