This time, our heroes must venture into the Fungal Swamp - an extremely rich and diverse ecosystem centered around The Great Mushroom Tree.

I like the visual design of this but gameplay wise this just tedious and boring and not fun. For me the worst DLC of all. But in general the devs do a good job, so its ok i bought this to support them.

Overall a deceptively strong DLC that adds a lot of value despite not really looking like it at first. - The new biome is alright. Behind Metal Terror I think, but lots of water and limited building space, but solid

Don't know why this is getting mixed reviews, this was my favourite dlc. It makes you play differently but I enjoyed that and its what I want from a dlc. I also though the unlocks in this one were the most useful out of

Both host and client needs to have DLC. Moreover, vanilla game is ruined by having some buildings from DLC left on the map, i.e. this is broken buggy mess, do not support those devs.

I'm Shrek, running around yelling "Get out of my swamp!!" as I clear the map with a op chainsaw and rail-gun. Alas, a Shrek green skin would be the chef's kiss.
