Shield Defense is a tower defense game, but with a fun twist. You can't shoot back. Your only offense is a good defense, because you can only use your shield to rebound the shots coming in on you.That makes it a lot more difficult to play and think about. You need to concentrate on your defensive skills more than in other games. Every 3, 4 or 5 rounds (depends on the skill level you choose at the beginning) you get a bonus point. Use those bonus points for bonus upgrades, rather than regular upgrades which cost money.
In between levels, you can upgrade your shield using the money you collect from blowing up the bad guys. Just don't spend all your money because any money you have left over earns interest in between rounds.
Hints and Tips
Get the antimatter shield (cost of three bonus points). At the later levels, you'll be facing fire from several different directions and you can't block them all. Heat seekers is another great upgrade (again, 3 bonus points). After that, increase the interest rate.
