Tall-nut is a defensive plant appearing in both of the main series Plants vs. Zombies games. It costs 125 sun and has an identical recharge time, but double the health of a standard Wall-nut.
The Riot Shield will deflect all enemy bullets, but the impacts will leave large cracks across the front of the shield, until the game reloads the image (it could overload the game eventually if it did not). The shield also greatly reduces explosive damage if pointed in the right direction, enabling the player to survive grenades and Claymores with little trouble.
A Bloonberry Bush is a Special Agent in Bloons TD 5. Once placed, it acts as a regenerating spike trap until the game is over. It grows five thorns per round, for a maximum of 200. Once the upgrade Tack Awesomizer is activated, the bush will be able to pop 400 bloons.
The Spike Factory is a special tower that, once placed, produces Road Spikes that pop bloons and disappear at the end of each round. Its special attack, Spike Storm, is capable of killing large amounts of bloons, destroying even MOABs and BFBs easily.
The Sentry Gun, also known as the Sentry Mechanical Firing Device, Sentry, Turret, or simply abbreviated to SG, is a building that can be constructed by the Engineer using the PDA, the Engineer's build tool. The gun itself is a tripodal device constructed of metal, team-colored paint, and a laser sight (when used with the Wrangler).
The Boom Shield is a bullet and explosive resistant shield wielded by Locust Maulers in Gears of War 2. Consisting of a central oval-shaped body bearing the Locust insignia that contains four retractable plates, the Boom Shield protects the user from head-on damage caused by bullets and explosions. The shield itself is highly resistant to damage, capable of taking direct hits from the Boomshot Grenade Launcher and Bolo Grenades without any loss of usability.
