The Battlefield Heroes closed beta period has today been reopened to the general public and to those who already have a key to play the free-to-play shooter.

The game has received a number of new enhancements, including improved hit detection, character balancing and new maps.

EA writes:

“The main thing we’ve been working on is building a new back-end and web system for the game. This means the Heroes website will look better and run faster and the forums, character profiles and stats will be leaner, cleaner, and meaner! We’ve redesigned and rebuilt the system that allows you to buy Battlefunds (virtual currency), earn Valor Points (in-game rewards), and to spend them on character customisation items like hats, weapons, and emotes.

We’ve also been working on improving what you see and feel in-game. We’ve fine-tuned our hit detection and made some balance improvements. We’ve hammered away on many of the bugs you were experiencing. We’ve even worked on some new customisation items and designed some new maps. These are things we will continue to work on throughout the beta and beyond.”
