Roadhog guide

Roadhog - Role Tank

Character abilities include the following:

• Scrap Gun - short-range blasts of shrapnel or longer range shrapnel aoe ball
• Take a Breather - restores 300 health, and disables movement for a small duration.
• Chain Hook - exactly as it sounds, a hook that pulls the target close.

Daopa's guide and personal take on this character:
With out playing the game or this character I will assume the chain hook ability will be most beneficial but it maybe tricky to use since you will have to make sure you hit the target with it. Offensive characters move very fast but if caught they will most likely be very easy to take down. Main task for tank role character is to protect your team, disrupt enemies and lead the charge.

Roadhog's hit points is currently set to 600 and a melee option is available which is a left hook attack.

Daopa's guide and personal take on this character:
Use charge to burst thru areas and drag enemies in your way. Fire Strike is great for long range damage application, focus on support targets. Shield is great to force your way closer to a group of enemies or to protect your teammates from extreme damage. Main task for tank role character is to protect your team, disrupt enemies and lead the charge.
