This was just a promo video showing the Ogre I purchased.
Yes, I am planning co-op multiplayer fighting against monsters like that. I have more work doing on the AI and path finding although it's mostly complete.
The gameplay will roughly consist of fighting one or several monsters while the flash light will play an important part. Using the flashlight let you see further but it will also attract the monsters.
Gameplay is not final of course, but I will slowly work my way into something playable.
One of the reasons I chose coop is because it's not boring to play your own game when it's multiplayer and because it's boring to play a death match when there are only 2 people online.
So I figured co-op is optimal.
