Not a lot of details above so I can understand why people are hesitant to try. Short answer - it's definitely worth a try. It's a 6-map co-op, and the gimmick is that every stage (except the finale) includes a panic event where you're riding on a big square moving platform at some point. The whole campaign's rough and unpolished though, and some parts don't have clear instructions so here's what you need to know: . map 2 - After you come out of the caves, you'll reach an unfinished bridge. The hint says to destroy a barrier like in map 1, but that's not right. Examine the pile of logs, then keep examining the end of the bridge to place a new plank one at a time. . map 4 - You have to do some Let's Build scavenging to build the platform before you can ride it, but only 1 of the 5 materials is glowing. The other 4 are: a car in the far corner, a pile of logs, some metal on the roof of the short building, and the mounted gun in one of the small rooms to the right of where you start. . map 5 - This platform event you may wanna lower the difficulty for. Unlike the previous ones, this platform's a raft but the enemies run on the water and don't need to climb to get on board - they just plow right at you. Your bots will be under seige most of the way, but they also don't detect the ammo piles on the "raft" so they're gonna run out of ammo halfway. Also, there's a part where you're passing between 2 "hills" that have 4 Tanks on either side flinging rocks at you. Bots will get incapped fast on higher difficulties if they're hit by multiple ones at once. - The first time the raft stops just shoot the metal wall like you did in map 1. The next time it stops though, you'll see 2 Tanks spawn from the top of the burning tower in front of you - ignore them and run to the safe room in the building next to the tower. . map 6 - Activating the radio the first time simply starts the finale music - examine it a second time to actually start the finale.
