I do not know if my insights on this game are helpful to you

1. the first few circles do not hurt, the energy to play full can ensure that they do not lose blood (drop a little blood, immediately be able to recover), so the poison came without too much tension;.
2. the first few circles, in the poison run poison, if you encounter a blocked bridge, in front of the room someone and so on, steel over on, steel but can consider the reverse run poison, around a large circle is also a first aid kit or a bottle of drink thing;.
3. a pair of many cases, it is best to beat a change of position, the use of card perspective to kill the first hand, because the enemy may inform your position.
4. when guarding the building, guarding the stairs is an easy way to be cracked, the best way is to find a small room that can see the stairs, and then use the card perspective to play the advance gun;.
