Infra-Red Sensors
A small description:
--
While vechicles are easily spoted when attacking beacuse of their light, the usage of IR sensor should be adapted.
It wouldn't make that vechicles wouldn't have to use light anymore, just in smaller numbers. (or prolly an advanced research could take care of that)
I think that IR sensors shouldn't be researched, beacuse it is very simple. It should automatically come with vechs.
E.g. vechs see-zone is 15 squares, enemy sees it as 5 squares... or less
Now it depends will it be used as IR LED's (light emmiting diodes) or another type of it.
The only bad thing is that (thumbsdown) IR could be detected by sensors.
