Patch:V Card
The V Card is a special item in Keen 5 used to open 'V Card doors'. They do nothing but sit and animate like a regular item and as such patches relating to them can be found on the page Patch:Items.
Don't lose V card on opening a door
This patch prevents Keen from losing any V cards he has when opening 'V Card doors'. This means once he gets a card he can use it as many times as he wants in a level.

Don't lose V card on starting a level
This patch prevents Keen from losing any V cards he has when starting a level. His keygems will still be affected. See also Patch:Level start.

Don't lose keygems or V card
This patch stops Keen losing not only his keygems but also his V card on leaving a level (but again, not when dying.).

Have one or more V cards when starting a level
This patch ensures Keen always has a V card when starting any level, including the map. He will be given the card whenever he leaves a level, but will lose it when he dies and retries a level. The value here can be other than 1 if desired.

Give\take something instead of a V card on level start
This patch alters what is affected at level start so it is not necessarily a V card. This variable can also be set to other values aside from 0 or 1; in this case keen will start all levels with 10 ammo. Notice that if Keen dies he will lose the V card but not what is given here.
