Hi, I was looking for how to get it a while back, and I couldn't find anything. After 3 friends and I came up with a surefire way to get it, I decided it'd be nice to let others know. Requirements You need at least 2 other people/2 other alts(Recommended 3 people/3alts plus you) You need to be working together to get it. You can't really be in a game with other people. These might be stringent requirements for some. I got on late at night(for me in the US) and found very few people on, and therefore very easy to get in our own lobby. It would be rude of you to try and get the achievement in an actual game, due to how hard it is without this strategy. Well, now that we have some ground rules of what you'll need to do this, we'll next cover what the achievement is. 2 people can get the achievement per-game, one on each side. If you have enough time, you can maybe fit more in there. The Achievement 'True Challenge' is and achievement in game that requires you to spawn in a giant before 15 minutes(before you see the 5 minute Armageddon warning). You can't place towers, or upgrade your gold mine. Rewards: 2,000 points, 5 cubelets, 20,000 exp. This is actually a lot harder than it sounds. However, with my guide, this will be a cake walk for most people. I always got it 3 minutes before the 15 minute mark. The Strategy Basically, you want someone on your team to build a bunch of towers, and then leave the game. When they leave, you can sell their towers which should bring you enough gold to get a giant in time. The only part you need to play is sending enough zombies to get giant. The other person should be upgrading their gold mine and building continues towers, poison and artillery are best. The person on the enemy team just needs to be killing the zombies right away, so that the exp gets to the achievement person as fast as possible. The best towers for this are 2 mage towers, and 1 ice tower. If you want extra death, or don't mind, place extra artillery on top of the mage towers. Only one person on each side should build towers, the person who gets the achievement cannot place a tower, or else the achievement is void. That's all folks, thanks for reading.
