The "League" achievements seem to be broken (for me at least). I played through the League with almost all classes, I get the achievement but it doesn't light up on the Achievements screen.
There's an even easier way to win:
Only get lvl 1 mages (5 gold).
The increased mana regeneration allows you to spam your main attack spell (I had some sort of earth missile) to destroy the enemy commander in about 3-5 turns. Upgrade your spell and your mana as much as you can!
2/5
Speed-up-option: +1
More turrets/floors/weapons: +1
More and different enemies: +1
(immune to turrets, creeps that attack the player, enemies that can only be killed by the player, swarms of enemies...)
It's a pretty good sequel. But why does the artillery not have any unlockable abilities? There could be a ton of things like Damage, Impact time (how long it takes until a bomb hits the ground), Price of ammo (so you can buy more ammo before the round) and the different skills (eg: Shockwave...) should work too. Maybe add the original Gravity launcher as a 5th weapon.
Here's a good tip: At the final boss, do not only spam Wizards, Golems and B. Dragons, but also spam Halflings. Yes, Halflings. They come so fast and are so cheap that the boss will be so busy with shooting the constant flow of halflings, that he won't move or only very very slowly. I beat him like that with my castle at full health.
Also, morrowind3, you are retarded.
