In 2022, Epic Games released its Lyra Sample Game. This high-quality sample game shows developers everything about making a third-person multiplayer shooter. You can download the Lyra Starter Game on the marketplace for free. Additionally they have videos & documentation explaining various aspects of the starter game.

If you’re going to be working on third-person shooters in the future, a good tip is to clone the project and export all of the animations. Save them as FBX files in a location you can easily find them. This will save you from having to buy any new animation packs for guns or do conversions from non-unreal rigged animations.
In the starter game, they have animations for shooting, reloading, equipping/unequipping, taking damage, and melee attacking; all for these weapon types:
- Unarmed
- Rifle
- Handgun
- Shotgun
All you need to do is select all of the animations in the folder (you can filter by ‘Type=AnimSequence’), right-click, and in the asset actions sub-menu select “Export”.

After that, you can import them by right-clicking anywhere in the content browser and selecting the “import …” menu item.
One thing to remember: Beware trying to import sub-folders. For some reason, Unreal Engine will ask you to specify the skeleton for EACH animation. Instead import folder-by-folder, without any subfolders. That way, it only asks you to choose the skeleton once.

I hope that helps some of you.
