Legend of the Frozen Empire: Shattered Ice, a coop mod for Rune: Halls of Valhalla.
It has everything, action, adventure elements combined with great music and level design.
Before getting started i have to state that i did not finish the campaign, but based on the first dozen levels that i played both single player and 2 man co-op, there is a lot of content to be explored here, a campaign designed for co-op with full understanding of game features (no ropes in co-op, fixed camera in a few epic places to name a few). I was bothered by the lack of a diffuculty setting/setting for enemy spawns but that is normal in rune (but if it gets love then i guess someone might do a few diffuculty settings for the mod). For anyone wondering patch version, i played with 1.07 and it worked, didn't try 1.08 yet.
Have a good one!
A nice new co-op campaign. Thanks for creating it. This is a nice way of playing rune besides all DM gametypes. I will play it with my mates and setup a server sometimes.
