1.) Quick revive, 500 points solo, 1500 co-op. In solo when you take enough damage to go down you pull out pack a punched pistols and the perk brings you back to life, in co-op it allows you to revive a team mate three times quicker.

2.) Jugger-nog, 2500 points. Jugger-nog allows you to take several hits before going down, this is vital on solo and on co-op.

3.) Speed cola/sleight of hand, 3000 points. Speed cola cuts your reload time in half, this prevents you getting caught between clips.

4.) Double tap, 2000 points. Double tap increases you rate of fire, it's good with slow firing guns like the G11 but not with guns like the AK-74-U.

5.) Pack a punch, 5000 points. Pack a punch upgrades your guns considerably, it is the most expensive perk, but having a pack a punched gun will increase your chances of survival in to the double digit rounds.
