"To sum up everyone's want's: Auto-hold fast forward, no kreds, pause button, and a pop-countdown for each level..." does the game creator even care what we are saying anymore?!!!
For beginners, just use Paladin and Mage. Paladin can cast holy aoura to get unlimited mana and mage can cast mass destruction. Killed the boss when at level 9 without even using a single potion.
Beat the game on my 2nd try. Here's how: 1. get the 2 fire sat. guns first and then do tier 1 upgrade for SAT and main gun till around wave 5. 2. get heavy machine gun and a barrier to protect it, forget abt light machine gun. Get the artillery upgrade too, it helps 3. upgrade the rest while building the rest of the turrets alternating between them (this is very important so that you have everything all around your base) with a few barriers in front. 4. build as much rocket turret as you can. 5. At abt wave 18, with everything upgraded, just sit back and watch your turrets take care of everything =)
Arrghhh... I've reached lvl 116 on Road track med and my firefox crashed.... Could have reached at least 120 or more. At least it saved my finished lvl and I'm rank no 1 for now =)
