[center]How to beat Beast on Insane
1. Pick Trenches map
2. When you start you will need 4 people or 5 to make it quicker to kill the cog or onyx guards.
3. Choose tickers, low cost, which means more money for beserkers at the end of it.
4. Continue to use tickers on waves 1 - 11
5. wave 12 alot of money stacked up for the zerker, and plow thru the onyx guards and prescott.
6. this is how i did it and got my onyx IM A BEAST! medal
We attempted with 3, got to wave 12, and lost so 4 is alot better chances, you might lose around 3 - 5 because they beef up the defences, but we got the hang of it and wiped em out and got the onyx medal.
Like i said this is how i did it to get the medal, just tickers and zerkers.
