Ebola monkey hunty is made by a company called cheapass games.
They come in envelopes, and come with the board on card in pieces and any cards you need for the game and then expect you to supply anything else like counters, "pieces" and dice since all th little fiddly plastic bits and dice and everything else are:
1) Expensive (in terms of total product cost)
2) You already have loads of these from other board games.
In ebola monkey hunt you play members of a research/crisis control team who has to retreive ebola ridden monkeys accidentily let out in an office. Whoever wins gets a hefty research grant, hence the use of you tranquiliser guns on other players rather than monkeys.
Killing Dr Lucky is effectively Cluedo in reverse where you're all trying to murder everyone and is also a cheapass game
and Orcs at the Gate is based on the knights of the dinner table comics
