You can get any logic-gate system to "play Doom". One of the ways I'm familiar with to do this with neurons is use an effect called "spike-timing-dependent plasticity". It's basically like creating a circuit with flip-flops and logic gates at that point and claiming "yo, I got transistors to play doom bro". I don't know if that's what they did here
