Great continuation of a classic franchise.
PROS: It has many missions that require multiple attempts to unlock and lots and lots of parts for your AC. The AC customization is highly detailed and in depth. Controls have been refined and feel great. The action is very fast paced and intense. Visuals are great, great effects for explosions and lasers. The scale of some fights is amazing when going up against the giant AFs.
CONS: Menu system is dated and needs to be re-done. Many missions can be completed in seconds, longest missions are under 10 min. It's fairly easy to win most arena matches with a pair of good machine guns. Limited maps with bland environments.
Overall this game is great and should be rightfully called AC5. This game is fun and easy to pick up. It also offers online co-op for the first time.
