Oh my god, that last boss is the hardest boss I have ever seen. It tears through my defenses with easy, even before its rage bar fills. And when it does fill, it instantly obliterates every single structure. How are we supposed to beat that thing?!
The key to getting money is combos. The key to getting combos is barrels and landmines. Use rambo, and upgrade and use barrels until you unlock mines. Then upgrade the blast radius and the ammo. Once you've done this, you can go to the test map, or any other map that has a lot of zombies, and get massive combos. At this point, money shouldn't be a issue, just the wait it takes to upgrade things.
Chaos, how does paying make it more boring? I would think nothing is more boring than waiting 4 hours just to level up your accuracy. Or farming for hours to get enough kills just to unlock a new weapon.
It would be really nice if you could use stars you've earned from battles to purchase passive upgrades. That's actually pretty much standard in good tower defense games.
