Fantastic game. One that I'd gladly pay 10 bucks for on Steam if it were a single player experience without the cash shop. Having to pay 50 real dollars to upgrade my workbench to level 5 without having to wait a week? Yeah, I don't think so :/
Helping people is really easy, folks. Give it a try: click the map, then the clipboard, then another person's name. Help out by speeding up the construction of their items. You don't have to travel or anything. Better than raiding people like a douche :).
i find this game impossible to play - the view keeps drifting towards the top right hand side of the screen and I can't control anything. Looked so promising, too :(
30 days! Just upgrade the car to level 2 engine, gearbox, tires and a bit of fuel. Then repeat levels until you get the hummer. Do the same with the hummer and go until you can afford the bus. Take the double cash bonus the first time it's available. Upgrade the bus the same way as before, only make sure to take the spikes and booster. Screw the gun.
It can be difficult to target some enemies when they are behind others. In particular I notice it's hard to target the pale hunchback enemies when they are behind bats.
I think the Super Hard mode should get it's own achievement for completion. Awesome fun game, though. I love setting up the wall spikes and some teslas and then just listening to the sweet chiming noise of bubbles bursting :)
