Kill Cards are a way of rewarding excellent action during a mission, whether it be extracting within five hours, not taking even a scratch of damage, or otherwise going above and beyond the call of duty. Kill Cards may include experience bonuses, new weapons and equipment, pre-mission bonuses and even a fifth team member - The Kit Carson Scout. One should strive to achieve as many Kill Cards as possible, as they are an excellent asset in any case.
They are randomly generated for player choice at the end of a mission with Distinguished results. Players must then choose one of four hidden Kill Cards to be revealed and unlocked for them. The reward will be immediately granted after opening the Kill Card.
Using a Kill Card
Kill Cards will be used instantly if they feature experience bonuses or weapons and equipment - the bonus or item will be immediately added to your profile. However, "Pre-Mission" killcards feature bonuses that affect your next operation, such as "Over Flight" which offers a 50% chance to reveal any placed items, or "Agent Orange" which removes 50% of all trees in the AO.
Many pre-mission killcards, despite their names, do not affect the mission itself. Some - "Detailed Paperwork," for example, will immediately raise your merit with no effect on the next mission you run. However, many do affect your next mission from a combat standpoint and can offer varying bonuses.
All of these killcards must be activated before your mission. This is done by clicking the desired killcard below your operations table next to the Colt Commander on your desk. Scrolling over each Kill Card will reveal its effect. Note: if you exit the Briefing screen or quit the game after enabling a kill card, the effect will not be present in your next mission and the card will be lost.
Earning Kill Cards
To earn a killcard, players must satisfy a mission requisite in order to classify their patrol as "distinguished" - generally, this requisite is directly related to the type of mission. For missions where the objective is to kill enemies, you will likely need to take no damage; for stealth missions, you will need to remain undetected, and so on. These distinguished missions directly affect the "Total Dist." stat in your profile, which can be equated to the amount of killcards earned, due to all distinguished patrols awarding a killcard.
Intel can also be used to buy kill cards, sacrificing potential benefits from briefing and AO information. One card costs 100 intel.
