Overtly means openly, and without any attempt to hide it. Overtly political, overtly hostile, not overtly.
It is the opposite of covertly and is nearly always used to mark a contrast, since saying something is not overtly anything implies it is so underneath. It is a favourite of criticism and of intelligence writing alike.
