Hi all,
This update's for the 0.2 alpha, you'll have to opt-in to play it:

Fields Rework
Fields has been reworked using the new scenario tech to intensify its long-range big-battle feel, and to generally make it more of a challenge. The map has been expanded westwards by about 500m (50% wider) to make it less of a corridor and promote different ways of tackling it. Spoilers ahead, so skip this section if you'd like to do the scenario blind:Spoiler
Heavies at the back changes- They're now a much tougher design, requiring the best AT guns of the period to pierce the frontal armour.
- They'll no longer charge at you. Instead, they'll hold the hill and fire down on you.
- They spawn at the start of the scenario, so you'll have to fight them and the light tanks simultaneously.
- If you charge them with greater numbers or they take heavy losses, they'll fall back.
