Barn

The Barn is where the final boss fight happens against The Cost Optimizer. In order to complete this level, you must stop at least 50 Prosecutors equipped with Grenade Launchers unplugging Winta from the Cost Optimizer Core.

Tips

 * Stay near a Vending Machine
 * Worry more about yourself, not Winta. If she gets unplugged, you can just plug her back in. If you die, you have to start from the last checkpoint (checkpoints are at every 25% of the download, which are usually 5 minutes apart)
 * Throw Grenades, don’t use the Bow. Unless you are extremely experienced with the bow, it is so much easier to throw the grenades
 * At the start of a wave, be right where the robots drop. This way you can take out at least 2 before you retreat to your normal spot
