Great FTP Game
DE has met all my expectations of a game and the experience it provides.
I like that it isn't on the normal trend of 12 on 12 pvp and constant respawn and kill.
The game has been designed that playing with 4 players of different frames you can conquer any of the factions if geared correctly. Or you can go it alone you can still accomplish all missions it just takes a little longer and many warframes in your inventory to manage each scenario.
Also with DE any in-game harassment is handled immediately and very thoroughly if reported. Education of new players is encouraged and antagonizers are usually shunned or banned from the game.
It is one of the friendliest groups I have ever dealt with as a game on helping each other and ensure we can all make the goal.
