Penitent Tower is the final stage of Valfross.
Objective[]
Reduce the entire fortress and everything in it to smoking ruins.
Strategy[]
An example of a quadcopter bomber. Logic Stabilisation is used to keep it straight in the air.
This is a legitimately difficult level with no easy solution - you really do have to reduce the entire fortress to smoking ruins, and it's not small, and it's not lightly defended. With over 30 axethrowers that can hit things up to 80 metres away for double damage, it is a daunting target to assault from the ground or from the air.
You can deliver Bombs to each of the five towers, making sure to hit the soldiers near or on them. Or, you can use a vehicle with Circular Saws or Drills to face them head-on.
If attacking from the ground, you'll need an armoured vehicle - preferably a fast one, with a frame built from sturdy blocks like Logs. The spearmen can smash weak frames, even if armoured. If you're carrying bombs, you'll need to keep them protected from axes and the aforementioned spearmen until you're in a position to launch them.
If attacking from the air, you either need a plane (with bombs) that can outrun the axes or a quadcopter that is stable enough to drop bombs accurately from 100 metres in the air. The Hot Air Balloon block can also help when multiple are used in conjunction. This can lead to instability, as well however, so a gyroscope of sorts can be necessary.
