Idea: Building Sentries on Buildings.

Papayas

I just thought of an idea with sentries and I think it would look quite cool.

What if you could build on top of structures. That way you could get better placed sentries that cover a better area because the sentries only cover the area in front of them. It would look quite cool as well if you see an Armoury with a sentry sitting on the top of it.

An alternative to this is that you could have upgrades for the buildings that make a sentry appear on top of it.

No, you can't reach them to build them meaning you require a MAC, and the upgrade means tonnes of new models for them and lots of upgrade requirements. Plus it's confusing for aliens, can you destroy the sentry individually or do you need to destroy the base structure? If you destroy the sentry individually, can it be repaired or does it need to be re-upgraded?

So in conclusion, -1.
