Team Fortress 2 unlocks: Engineer

1- Main Weapon: Double-barreled Shotgun – Texan pride! 
• Pros: great short range damage. 
• Cons: slower rate of fire than the regular shotgun, as it is reloaded after each shot.

2- Secondary Weapon: Girojet Pistol - a gadget born in the Cold War, a minirocket handgun. A more appropriate and less futuristic alternative for the previous Rail Gun.
• Pros: good damage. With a sound that is not associated with shots (can confuse the enemy). 
• Cons: needs to accelerate (no full damage when immediately leaves the barrel). Slower rate of fire than the regular Pistol and not as accurate. 

3- Melee Weapon: Blowtorch – an Engineer’s essential.
• Pros: builds faster. Fast rate damage, can ignite enemies (useful against Spies).
• Cons: consumes fuel over time. Needs to be lighted each time is selected.

4- Hand Grenade: EMP grenade – if Engineer knows how to build it, he knows how to destroy it. The explosion deals powerful damage against buildings (sentry slayer) and detonates Demo’s stick/pipe bombs. No damage against humans. It’s interesting now to see Engineers helping to breach the enemy’s defense.
