Bethesda are still regularly rolling updates for Fallout 76 regularly and the latest one brought the quality of life changes that should offer clarity and fewer expenses during gameplay. Energy Weapons now benefit from armour penetration.
Fallout 76's new big thing are Public Events that are basically some of the existing events with additional quality of life improvements. Players will have access to free fast travel while participating in these, junk will not be dropped on death in Adventure Mode and they will be more noticeable on the world map.
Furthermore, hovering over an active Public Event on the world map will offer additional information that includes the number of players who are participating, time since the event started, general difficulty rating and the type of gameplay offered by the event.
According to the patch notes, the difficulty rating will scale in complexity of the event's objectives rather than enemy difficulty so bullet sponging will probably be reserved for boss creatures only.
Nuclear Winter has received a new map called Morgantown where players will duke it out in "diverse terrain" with new enemy creatures to accompany them. Matchmaking for NW has been improved so players will be matched with peers from all over the world. It remains to be seen if this will improve or ruin the experience due to latency.
There are now six new Morgantown-themed rewards players will be able to unlock by completing the accompanying challenges.
As for design changes, Energy Weapons will now benefit from armour penetration effects across the board. This means bonuses from Perk Cards will no longer be wasted if you equip them along with a laser spitter. An important note is that Energy Weapons will still use Energy Resistance (ER) for damage calculation so the armour penetration benefits will actually make the weapons bypass ER, not armour.
Sadly, the new weapons that can be bought from the Purveyor don't include Energy types. It is five new melee weapons but if you stashed a Gauss Rifle for later use, it may be a good time to whip it out.
You can read the full patch notes on the official website, along with a ton of bug fixes.
