Nearly finished the campaign.
My ordeal: aarghghuaaha
It's always nice to pick up other worms games, just to see what ideas are in it regarding schemes, weaps, maps and all that. Inspiration and what not..
Anywho, Battlegrounds is one of the worst releases. It's basically Worms Revolution (with all the nays of that game (shitty rope, worms and crates falling off cliffs out of nowhere, bugs, etc.), but it has the additional **** of having three different kinds of textures that are REALLY hard to keep apart. Often you find yourself jumping on a chunk of land that proved to be just background texture, other times you try to dig into indestructable land, cause it looks just like regular land

And this happens after 20 finished missions.. it's not a rookie thing.
The missions are dull and uninspired, supposedly the whole campaign plays in a museum, but there is absolutely nothing in the maps that reminds you of that setting. The maps are also identical, no changes in texture, just in map layout.
Also, there are checkpoints on the map that you can enable to save the current state of the mission.. unfortunately it ends your turn.. and sadly, at times you HAVE to pass through them, so losing your turn is not even an option. That's the kind of choices the devs make that I just don't understand. (Same with the addition of anti-darksiding weapons like the bunker buster and even worse Boggy B..)
Rating: 3/10
Buy this for your mother-in-law.
edit: also, no online, and the AI is a combination of CPU5 skills with uhhh.. well.. nothing. If you're in clear nade trajectory it's 40 damage per turn. If you're not.. you might as well take a five hour break and return to find your worm with the same HP. It is absolutely retarded. No words can describe the utter boredom of playing a fort game against a computer that hides in open air on the front side of its fort and that takes 50 turns just to make 3 holes in your fort..
