This game grows on you and gets you hooked
When you get to 30 you are able to do Duo's, Hard Alerts and Raids. Duo's make it easy for characters with not to great gear to get a chance to play "older" content in a new setting. You get another level 30 player with you and the difficult level is higher then the regular solo instances on lower levels. Hard Alerts also give you the same. Some of the older alerts but also some new ones. Raids are the greatest challenge in the game, with firece bosses and a lot of friends to help you. This gives the games some depth. Challenges also give you easier content to do when you don't have any gear, it allows you to revisit older and newer content.
All though most of the game is solid in every way, it still lacks some content. Don't worry though, it there will be new content every month. So there will be more to look forward to. There are also some glitches and bugs that can be annoying, but they get fixed and hopefully will be gone for good not too far in the future. This game doesn't require you to know the DC Universe. It shows you a Superhero game which doesn't require a lot of knowledge to really enjoy the game. It's a really fun game to play and it's not a hard game to like
