There's a bug, you can research every tower in game with only 500 research points: farm 500+ research points, start any level, reserch any tower, press Retry (in Menu), tower researched, and research points refunded back.
Bug: Enemies killed outside the screen (especially at the top) do not drop money. (Actually they drop, but money just disappear because they outside the screen...).
This is a great game. The first multiplayer flash game, which I rated at 5. But I think that there need some improvements/changes. 1) Option to sort weapons/gears by DPS, type (blunt, blade, long, shotgun etc.) and other parameters. 2) Ability to hide equipped weapons/gears in inventory. 3) More information about the zombies, traps and defenses. 4) We should be able to send survivors to the gardens/collectors to increase it's production rate. If someone takes care of the garden, it will give more food, it seems to be more correct than garden which "works" by itself. 5) Also i think, that we should be able to send engineers to the construction/upgrade to speed it up. 6) Some improvements for firearms in "offencive slot". because at this moment they are totally useless. (I'm sorry for any errors, English is not my native language.)
Once we get a hit, should be a time during which we are immortal one or two seconds. At this point, the purchase of additional lifes is useless, because 50% of the game objects are kill instantly, regardless of the number of lives. (Sorry for bad English. This is not my native language.)
Accumulated $500,000. Looked at her and looked at the money. With YaoMingFace went to Saudi Arabia, bought seventeen new wives and Ferrari. Problems? *trollface*
The game is excellent, but I would like to see a version without the radar, showing the location of enemies and without the music, which also shows that the enemies in the room. The game would be much more horrible.
I do not like the levels (last levels) where the boss kills the whole army with one blow. But the attack of your strongest unit takes 0.0...01% of its health points. I think that the complexity of the game should not be based on an huge imbalance of forces, becouse it tire very quickly. Previous parts of the game I liked much more. 4/5
In place of the guy (at the end of the game), I would be looking around in the sky looking out for the angry flying penguins. 6/5 :) (Written with the Google Translator)
I think stats in game are normally balanced. You don't need lots of stamina (and agility) to complete game. Most important stats: speed, reaction and health (it must be always 90%+). >>> Sorry for my bad English, it's not my native language.
