John realised that using the standard Logic Bombs failed to leave so much as a scratch on the machine behemoths' bodies.
Those machines were huge for an explosion to affect them, and the reinforced alloy was designed to withstand the blast, making it harder to kill these things.
It wasn't until he combined the bombs with his Code Destruction ability that he found a breakthrough.
The Code Destruction ability acted as a digital corrosive, peeling away the hardened shells of these behemoths. They didn't leave behind the usual holes, only shallow gaps in the machine's sturdy armours. Once the defensive shell was stripped back, the Logic Bombs finally did the trick, detonating within the vulnerable internal structures.
Once he figured out the way, He started killing thousands of these giants while simultaneously wiping out the weaker machine units that tried to swarm him in the process.
