Its not this one, the one you're refering too is Legends of something. They give beta keys on Kotaku for the one you're looking for.
 
This one is made by the Savage 1 and 2 people. And as i reported in another thread, you should stay away from this game and the community of @ssholes it contains.
 
EDIT : its league of legends and here's the kotaku link! 
You're welcome.

I haven't encountered any assholes playing HoN. It's a lot of fun.

Because of what i said in this thread. 
 
Avoid this game if you can. The community is by far the worse i've seen.

Then its unacceptable. A game shouldn't be for elitists jerks, it should be for them, for you, for me. Everyone. The fact that i've never played dota before should not exclude me from a game by the devs and even less by the people playing in in the NOOBS section. I said it and i'll say it again. Avoid this community if you can and put your money where you can find a nicer bunch of people.

I think it is funny that the developers of the original DotA are making a new DotA game that plays like DotA but doesn't walk the parallel line as closely as Heroes of Newerth does despite HoN not being developed by the DotA developers.
 
Also to demonbear, yes there are a lot of elitist jerks, but you are expecting "helpful hints" and what not?  I mainly play competitive online games and in these types of games rarely ever do I see players looking for "helpful hints" you have to learn for yourself and not let other people get you down in the process.  There are many people out there that will be willing to help you, however, they are generally not as vocal as their asinine counterparts.  I think it is because most figure "I learned on my own, you can too."  Learn by playing, learn by watching.  That will answer most of your questions.  I mean are you really going to let the opinions of other people, on the internet, hinder your own experience of the game?  I don't think I have ever cared about what anyone says to me in a game online, good or bad (and I rock in TF2 :D)

As a dota player for three years, and being in beta for both HoN and LoL, i can easily say that HoN is hands down better in every thinkable way. From a graphic stand point, i generally like the partly cel shaded look of LoL, but it just gets too confusing and way too bright in clashes. HoN is darker lit and has a darker more serious kind of tone. HoN is also m u c h  more similar to dota than LoL, in every single way: Heroes, items, map, game rules, creeps, spells, and overall community. This ain't a bad thing, HoN even improves on a lot of things that are lacking in dota. The hosting system of HoN is brilliant and simple aswell, it's easy to use and very fluid, i also happen to like the friend and chat options aswell as clan possibilities. Overall i would recommend HoN over LoL, as it looks a lot more like dota, which i love to death.
