Wave 40.
When I die, I basically lose, because since it's moving forwards, when I respawn, I die again. This cycle repeats until the base is destroyed.
Bush Whacker 2 is a non-violent game set aside from the violent ones we're seeing more commonly throughout everywhere, and I see it as even as if it's a break from those games. The concept is fun and friendly and it doesn't really give a really big advantage if you use your money in this game. The only thing it does is give small advantages over other people and makes you cooler. And it also makes you progress through the game quicker, but I wouldn't do that, as you might miss some of the little details in the game. So overall, if you're tired of the "kill" type of games out there, I recommend this game to you. But, if you like the "kill" type, then, if you want, move on.
If you play BW2 backwards, it's about a guy re-planting bushes with his magical sword and running away from a princess while stealing items from people and hiding them in bushes. Later, he repairs his ship and set sails away form the islands.
