Instructions
Click the "Store" tab and select "Heavy Cluster Bombs" and "Hellstrike Barrage." These two items do heavy damage to enemy robots and are a big help during the mission.
Click the garage tab. Prepare for the mission by building a robot with heavy defense and close range weapons for the front line, as well as one with long-range attack capabilities. Create another robot built around speed. Once you are pleased with your designs, click the "Missions" tab. Select "Disappearance of Kraus" and click "Accept."
Left-click on your robots that have the fastest speed and click the green arrow buttons on the left of the screen. You have two minutes to get your robots to the other side of the screen. Every robot that makes it to the other side will deplete some of the "health" of the base as indicated on the top right hand side of the screen.
Click the robots with long range fire next, then click on the green arrow buttons to send them out. These robots will take out the enemy robots obstructing your speedier robots, allowing them to destroy the base quicker.
Click on the heavy cluster bombs or hell strike barrages and click on the enemies if they are crowding your robots. Click on the robots with heavy defense and send them out to block any lanes where enemy robots have managed to smash through.
Bring the health of the enemy base down to zero before the two-minute timer runs out and you will have beaten the level.
