Here are the secret medals and the mods you get from them: Vegetable Guy: In the Market map, destroy all of the fruit. I just used a level 1 mercenary with basic weapon. Unlocks Tin Man mod. Game Breaker: As an Engineer, put a Tesla Coil on the 2 jumping pads in the Base map. Unlocks Wizardry mod. Party time: On the first map, Station Repair, when you are supposed to fix the generator, don't fix it, just crawl out the way you came, and then go back to your starting point, jump up, then go down to where the box and neil is. Go past the armor, and you should see a rofl face. Go in that room, and you unlock the last mod, Fiesta.
Had a really weird glitch on W-2 where I don't have any platforms, and I'm going into space, but I can still control myself, and I get farther and farther away.
For Swarmling II, it still says "Your swarm's smallest and weakest warriors. They use their teeth and claws to attack foes, and can be vicious in large numbers" yet still captures more territory than all of my other troops combined.
Sithicus said"Just got all the units and maxed all xp. I see a lot of people commenting on the lack of use of the hero in later stages, and this is because the hero is just a loss catalyst, not a one man army. You need to all forward with your army and leave the hero parked at that start, and the rest is just picking the right accessories and the right units for the various challenges, like a good General does, and oversee victory from safety. The only trial I found challenging was the Golem, who pretty much oneshots everything, so the answer lay in the Hobbits, Goblins, Vampires, Mages, Succubi, and Witches. This gave me enough ranged dmg to burn the Golem boss down while kiting slowly back to the start. The rush of my cannon fodder goblins and hobbits and vampires slowed the golem enough to bring him down one last retreat from the start. Hope this helps." and it works. The Colussus is the golem.
