yes and no. you could certainly enjoy it and play enough to know you wanna spend ~40 bucks on it. so i'd call that "getting into it".
but you wouldn't spend further 100's of hours without spending that unless you are chronically third world.
it'd be so annoying and timewasting without some basics like currency/map/premium tab and maybe a quad tab at least, idk why you would do that unless making some retarded stand about spending some money on a game you like.
and in a more pedantic sense no, the early access is currently a buy-in only, so you can't.
that said the next update launches with a free weekend, but for all we know it could be a terrible experience with lag, DDoS, and bugs in those first days after patch. (they used to have mostly smooth launches except Ultimatum league, but lately things have been fucked)
