(adsbygoogle = window.adsbygoogle || []).push({}); I've only used pack a punch twice but it is very good, I put in the thompson and the browning and I got the "Gibs-O-Matic" (upgraded thompson) and the "B115 accelerator" these both shoot lasers which make the guns more powerful and there is less recoil and I think more ammo.
However, the only way I can see of getting ammo is by getting "max ammo" and i'm sure not whether you can go back to where you got the thompson and get ammo although I doubt it.
The Pack a punch machine is worthwhile. To open it you have to go to each of the 3 teleporters and link each one to the mainframe, (the circular pad infront of the pack a punch machine) you have 30 seconds for each link.
Then pack a punch is 5000 points I would also recommend buying the "bowie knife" (which is a 1 hit kill knife that replaces your normal knife for 3000 points) as well as having juggernaut and speed cola. After a while the bowie knife is 2 hits for a kill but I still use it against the dogs as it is very effective.

oh yeah and my friend said he upgraded the colt and he got a grenade launcher on it I don't know if this is true or not. Everyone try each gun upgraded and tell me what you think of them!

you can buy ammo for upgraded weapons if the weapons are on the wall for 4500 and the colt does upgrade to a rocket launcher thing with 40 bullets and can be used in last stand

Did the magnum Just quicker fire rate and 1hit kill on round 20+ i found

Nah don't worry there all good and I don't play World at War any more its all about Fifa can't wait for Fifa 10
