How to unlock the Smash Master achievement in BINARY DOMAIN - Definitive Guide
An excellent place I found to obtain finish up this achievement is right at the end of Chapter 2. As you are about to take an elevator out of the sewer system, the two squad members whom you did not take with you have fallen under attack. You head back solo to rescue them. After successfully doing so, you head back to the elevator, but are ambushed by what seems like an endless supply of "Monkeybots." Just stand at the top of the ramp leading up to the elevator and hammer "X." You'll have the chievo in no time.
Kill 50 enemies with melee attacks. You should get this with little effort. Simians and Needle Bugs are easiest to melee. You can also shoot off bots' heads then melee them or pick up a shield and use that to get kills. Kills are cumulative and carry over into chapter select and additional playthroughs.
This should come naturally, just walk up to a weak enemy and press X and you should get the Smash bonus. If for any reason you are having trouble with this at the end of the 2nd Chapter when you are in the sewage plant after saving your comrades, you wait for an elevator and Crazy monkey bots, the small brown ones will infinite spawn and will keep coming to you. Just walk up to them and press X, they are one hit, you should get this is no time as they clump together and you can get multi-kills. Make sure NOT to get on the elevator until you are done. Run around the elevator if you are hurt too much.
