Monster Mash Hints, Tips and Tricks: ----------------------- Submitted by: RM Build Guns and Lightning Towers along roadside, and basic towers around, making a circle leaving the centre for a energy tower. Make such arrangements in EVERY turning of the road to win. Having one high level tower is usually better than several lower level ones. To kill powerful bosses later in game, Guns and Lightning Towers no longer work. What you need is massing high level (4 or 5) basic towers around an energy tower (> level 2). And to further increase your chances, use Power Ups such as rapid fire, power fire and slow monsters as a combination. I found I can build up my "power up's" by playing the game until the boss round.Then I click on restart level and all the "power up's" I collected are there.After a few rounds I have built it up to 9 for each power up. You can create SUPER towers by surrounding towers with energy towers. A fully upgraded tower surrounded by energy towers is an amazing thing to behold. Basic towers are best for killing the bosses. Forget trying t o use the lighting and guns towers for the bosses, because they just don't do the job.
