This exists as a normal ability in Harbinger. Mod-chips upgrade your weapon capabilities and are easily inserted and removed. Just in the demo I started playing like this:

"Oh, I'm up against Bugs now. Well, I'll just remove the 3 Plasma mod-chips that I needed against the Infanty men and insert my 3 Electricity chips, 'cos they fry bugs good."

And barely a bug touched me, just like the Infanty before hand. They couldn't live long enough to challange me, and since I could fire from a distance, I just pealed off a couple of shots once in a while to hit anything ahead of me. It was boring and unchallenging.
