Ya, it's 100% free to play (unlike CS:GO crap), it has cool graphics (unlike CSGO crap) and offers permanent weapons (unlike CSGO crap). However, HD textures are missing and the competive scene isn't as big as it used to be since lots of players quit or moved over to CSGO since the game hosters (AEG) went into total P2W, though they're going back to how the game used to be, players and competive scene are slowly returning (inb4, I don't hate CSGO).

Tyler aka Skadoodle used to play AVA before he went over to CS:GO for reasons above.

It's totally worth playing, especially if other shooter games are being bored for you.
