If you are a year one Destiny veteran you probably remember the insane range that all Warlock melee abilities held, it is one of the many reasons I was proud (and still am) to be a Space-Magic-Wielding-Warlock. Well, the Synthoceps turn that right around and give the front line of defence a little more reach.
The Synthoceps are a subclass neutral Exotic that holds the Exotic perk, Biotic Enhancements, which provides increased melee range. It is not a trifling difference, with the Synthoceps allowing your Titan to almost double the initial melee range, in fact, if you were watching it in the third person it would look quite comical. Biotic Enhancements also provide a damage bonus to melee attacks when your Titan is surrounded, which will see an enormous amount of use in all forms of PVE activity. The Synthoceps allow a Titan to literally punch their way out of trouble or just dealing additional damage to the heavy hitting Major enemies.
The Synthoceps will function in both PVE and Crucible scenarios, like many Exotics in Destiny 2, but based on the benefits it seems like it would be more useful in all forms of competitive PVP, at least ones where closed-ranged combat is commonplace. If you think about it, the additional damage when surrounded would still provide you with a disadvantage if you happened to land in the midst of a team of hostile Guardians. You will either be shot or more likely punched/palmed/stabbed to death. You may still take one of them with you, emphasis on ‘may’ but the risk is not worth the reward. For that reason, the additional damage will be used more often than not, in PVE activities, but can also be easily mitigated by Lifting yourself out of the surrounding danger and gunning them down.
The additional melee lunge range is a different story, for one single reason – it gives you an advantage. The average Guardian takes about two melee strikes to put down, which means that there is a significant advantage for whoever hits first, which the Synthoceps can almost guarantee. Not to mention, it can allow you to boost closer if an enemy tries to back off or run away. A quick lunging punch to the back can see them to the respawn screen.
The Synthoceps can be acquired through a random Exotic decryption or purchased from Xur if he happens to carry it in his inventory.
