A new update for Bungie’s Marathon is available now, and it’s got some interesting tweaks to weapons along with an extension of a limited-time mode.
The Vault Breaker PvE mode has been extended to Aug. 18, allowing for more play time and testing for the eventual full-fledged PvE experience coming in September. Along with that, several guns have had changes to optimize the player experience.
The V22 Volt Thrower got a nice damage buff in the update, along with changes to the KKV-9SD. Beyond that, the update mostly includes bug fixes and optimizations. Here’s everything new and different in Marathon today as part of its latest update.
