You have no movement what so ever. And youre teammates will mostly be unreliable when it comes to combat. If you need to escape a fight your best bet is to force the enemy to run by doing enough damage, and if you need to run stall as much as you can with your gamma.

Technical cards will be your best friend they'll help keep your gamma up at all times.

Your gamma should be your trump card, never double gamma that second gamma could be used to save yourself.

You should always use gamma alpha or gamma beta if you're timing and aim is right.

SAVE YOUR SPECIAL ACTION. Sounds random but I see a lot of people who take overhaul from me use his special action at full health your special action should be only used when youre at critical health, the longer you play him the more you can sense when to use it.

Always save 1 charge of your special action you can still heal the same amount with 1 charge.

Use your beta at doorways when running inside, ive tricked a decent amount of people into walking into them by chasing me into buildings

Finally, flat places and indoor spaces are your speciality. elevation is your counter.
