Ringfall TD

Eight lanes ring a castle, and the swarm is coming down every one of them. Ringfall TD is a co-op maze tower defense for up to eight players. Each player holds one side of the ring: wall off your lane, set turrets into the walls, and stretch the creeps' path as long as it will go before they reach the far end. What gets through doesn't just vanish. It runs on into the next player's lane, and whatever makes it all the way round attacks the castle in the middle. Catch your teammates' leaks, and count on them to catch yours. Three factions • Humans: rapid-fire guns, rockets and shells that wear the swarm down. • Organics: poison clouds, acid sprays and spines that eat through whole packs. • Aliens: lasers, photon blasts and plasma lances, slow to charge and devastating when they land. Twelve buildings each, towers that keep on upgrading, and six ways to choose what they shoot. Know your enemy Six damage types against four kinds of defence. Bullets tear through flesh but glance off carapace, poison seeps through psionic shields, and blasts swat flyers out of the sky. Read the next wave, then build for it. Crawlers, Rippers, Juggernauts, Serpents, Wyverns and more, with a boss every tenth wave. No last wave The waves never end: see how far your team can hold. Long waves speed up, so nobody sits waiting. Rare finds Now and then a creep drops something: gems that turn a tower's damage into another type, Overcharge Cells, Stasis Mines, Life Shards and Bounty Charms. Bosses always leave a trophy.
