A Excellent strategy on any level and any difficulty it to trap a final zombie within a wall or barrel... no auto wave turnover! just sit back and build your defence!
I am giving it 5 as it is the best defence game I have played. GLITCH: when I first played it, on level 20 I let all the lead balloons pass. It won't let me have the badge now, even when I go from the tart on a different level.
I played this game before their was badges and coundn't get past level 2. I played it again and I completed the campaign. I always try to 'demoralise' my opponent. TIP: on the last level, I won by just sending tank after tank, no infantry whatsoever. I hadn't even got the tank upgrade. Nice game
I think the command system needs to be simplified. Maybe just select then right-click to move troops perhaps? I was low on morale so I kept my units in the trench but then a few idiots tried to make a break for it (without me telling them to) and so I lost due to morale. 4/5
Quite a good 2-D shooter 3/5
Good points: fast gameplay, plenty of upgrades, your ship changes as you upgrade
Bad points:
lack of options such as saving or unlockable modes, sometimes the particles get over-the-top
