With combos (http://onslaught.playr.co.uk/)!

Have fun. :)

made it up to wave 29, but not sure if it was this computer that I was on, but the game started to slow down everytime around wave 23 making it hard to click and move around for placement of the towers. all in all it was fun, I'll try it again when ever I get my old system back up and running

What mode and map did you use Timber? I'm currently on wave 391 and I think I might just let it run overnight to see what happens :rolleyes:

Oh this is fun :)

Its just not that hard. You don't need to think, just upgrade towers as you have money. Get a railgun, put it at the end of a long stretch, and you can take 50 waves at once.

On "hard" difficulty and the standard (first) map, it's tough to survive long enough to get a tower to max damage, which of course is a requirement for the combos to start working.
