I Am Security is a mobile game you can get on Google Play. It is free to download. It is a tower defense game. You play as a security guard. You protect a building from waves of strange creatures. The game has in app purchases. You can buy coins and gems to upgrade faster. There are also ads. You can watch ads for rewards. The price for things inside is okay. It is not too expensive. But you can play without paying. I played it on my phone. It works well. The graphics are simple but nice. The sounds are good too. It is a fun game for short breaks.

You play by placing guards and traps. You have a top down view of the building. Enemies come from different doors. You need to stop them from reaching the core. You earn money for each enemy you defeat. You use money to buy more defenses. You can upgrade your guards during a round. The best part is the strategy. You need to think about where to put things. My favorite part is the boss fights. Big monsters come every few waves. You need a good setup to beat them. It feels great when you win. The game gets harder slowly. New enemy types keep it interesting. You unlock new guards as you play. There is a story too. It is about why the monsters are attacking. The story is simple but fun.

This game is like other tower defense games. It is similar to Kingdom Rush or Bloons TD. But it has its own style. The setting is different. You are inside a building, not a kingdom. I recommend this game if you like tower defense. It is easy to learn but hard to master. The free to play model is fair. You can progress without paying money. It is better than some similar games with too many ads. The gameplay is smooth. It does not crash often. Give it a try if you want a good mobile game. It is perfect for waiting times or a quick game before bed.
