Dog-people co-op shooter Gravhounds has a free Steam playtest through Monday

Gravhounds’ free Steam playtest runs through Monday, offering a co-op wave shooter with dog-people characters, buildable cable routes and light tower-defense elements; players also mine resources and fling them across the map with a gravity gun.

The writer says the game borrows Helldivers 2’s spaceship home-base setup but does not otherwise play much like it, while describing the shooting as fun and the movement as good. Players can join via the “Join Playtest” button on the Steam page.
