| Everything Is a Projectile Ultimatum479 | Your creative use of the city as a weapon adds this Mutation's Mutation Strength to your Attacks but also earns you the wrath of a 20 Energy Militia which Attacks you for 5 each round until slaughtered. |

| Reanimation Kevan | Lose all of your Mutations, and gain those which you had at the end of the previous game. |

| Unexpected Weakness Kevan | Flaw. (All players pay their bids for this, except for the lowest bidder(s), who must take it and cannot discard it.) Secretly choose a number between 1 and 10, before the game starts; if anyone uses this number in an Attack against you, you keel over and die. |
| US Military Kevan | The US Military have 100 Energy. At the start of each round, they will decide to Attack the Monster with the most Energy for 20 damage (or as much of 20 as possible), and to spend the rest on Defence. |
