I feel the game needs more improve alot more as it some times asks you to do the same mission again but heres my review
Defiance is a big, bold, ambitious, and ultimately fractured game. After a launch that could optimistically be described as bumpy, the online game continues to stabilize. That doesnt justify some of the other problems inherent to Defiance, but it does make grading it a bit tricky. When it works, Defiance is a fun and addictive MMO with solid gameplay and content for months. When it doesnt, its maddening.
Main events will vary between a handful of different types as well, but they put you and 50 or more people up against a giant boss-like monster. The methods change a bit, but it always comes down to shooting a monster in sensitive spots until it is destroyed. Once it is, youll receive experience, credits, and the odd item.
These random events are fun to jump into, but a bit more variety would be nice. This may change through updates and expansions though. That said, the first few times you ride from spot to spot with an entire herd of other gamers, engaging in an Arkfall from start to finish is one of the most impressive moments youll find in console gaming
