Siege Defense Games

In Siege Defense games there's a castle, a tower or a base you have to keep standing while enemies attack without letting up. With more than 200 games, it's one of the largest defense sections on the site.

What sets them apart

A siege, originally, is when an army surrounds a fortress to capture it. These games put you on the side of the defenders, and it shows in the setup: the place you're guarding doesn't move, the enemy comes for it and you decide what protects it. Compared with other defense games, the pressure here is constant and the goal is almost always the same: don't let what's behind you fall.

There are a few ways to go about it. Classic tower defense games like Stark Tower Defense, Garden TD, Underwater Tower Defense, Rise of the Tower and Bomb It TD are built around placing defenses along the path. Fortress and castle games, such as Frontline Defense First Assault, Avatar Fortress Fight, Troy and Onslaught Defense, tend to be about recruiting troops and reinforcing walls. Bombs and Zombies, Zombie Trailer and Monster Hunter rely on hordes of monsters or zombies. And in some you defend with a single character who shoots, like Strong Bow or Defender Hold the Holy Pig.

Getting the most out of them

The important thing is to upgrade your defense well between waves. Keep some money in reserve for when a stronger enemy shows up, and don't blow it all at the start. If the game lets you upgrade skills or weapons, prioritize what affects every enemy over what helps against just one.

Watch which side they come from and what their weak points are. In a single-archer game like Strong Bow, focus on the enemy closest to you. In tower games, spread your defenses out rather than stacking them all in one place.

And don't be discouraged if you lose on a particular wave: losing usually shows you what you were missing, and the next run goes better.
