Mothergunship and Train Sim World 2 are free on the Epic Games Store this week

Weekly double giveaways continue to drop from the Epic Games Store, and the latest arrivals are Mothergunship and Train Sim World 2. These have replaced the Verdun and Defense Grid: The Awakening freebie duo from last week.

Developed by Grip Digital and Terrible Posture Games, Mothergunship offers a bullet-hell first-person shooter experience with extremely deep gun customization elements, from twelve-barrel homing missile gun to a lightning spewing shotgun, and much more. Co-op is also included, so you can fight the hordes of robotic invaders and massive bosses with a friend.

Here's how the Epic Games Store describes the title:

MOTHERGUNSHIP is a bullet-hell FPS where you craft your own guns, fight huge bosses, and defeat a robotic alien armada that conquered Earth. Face off against overwhelming odds in brutal, non-stop combats where thinking on your feet is the only way to survive.

Alongside it arrives Train Sim World 2. As evident by its name, the game is a train simulation, and it boasts highly authentic locomotives, routes, and locations. Developed by Dovetail games, the game has you hauling freight across mountain routes in the United States and tackling the rush hour of the London Underground among other popular lines.

The Epic Games Store description is as follows:

The evolution of train simulation! Master iconic locomotives on high-speed services, long freight hauls or precise commuter traffic, and get creative with customization tools in this advanced sequel. Climb into the cab in Train Sim World 2.

Here are the system requirements for the two games:

The Mothergunship and Train Sim World 2 giveaways will be available on the Epic Games Store through next Thursday, August 5, for claiming. A Plague Tale: Innocence and Speed Brawl are up next on the giveaway schedule.
