@Matzerath - can you give an example of what you mean by mixing weapons? (I'm imagining an artillery cannon that launches infantry soldiers)
Yes, I'm feeling my idea would lean towards the limited and ludicrous, ha ha.
Other than that, what I had in mind were settings so you could, say, design weapons with different parameters -- like changing the zombie attractor so that it repels humans and zombies alike, or a 'bomb' that changes zombies to humans. Or as another example, making the infantry into a sort of medical team that 'shoot' cure. A level utilizing all these could involve reverting and airlifting as many humans as possible before the time-limit is up.
Though this all might still be ludicrous!
