LudoChrono - Last Heroes

About Last Heroes, from BoardGameGeek:

A dimensional gate has just opened, and monsters are surging over our world. You have been called to kill them and steal the artefacts from the monster bosses. These artefacts all together allow to close the gate open by the Chaos monsters. Use your weapons cleverly and help your fellow hunters by providing them ammunition, but in the end, only one hero will build up their name and get glory. During your turn in Last Heroes, you choose one of the weapon cards from your hand and play it in: Your supply area (with its ammunitions then being available to opponents), or Your attack area (using the ammunition available in your or the other players' supply area). Then you can attack one monster provided that you have the required weapons. When you kill a boss (in the third row), the player who has made a dent in the second row gets an artefact. If you directly kill a boss (without making a dent first), you need more weapons but you score the artefact for yourself. The game may end in two ways: Immediately when the players get all the artefacts (in which case, each Artefact scores 5 points), OR after ten turns (in which case, the Artefacts do not score). Last Heroes is both collaborative and competitive. You need the other players' ammunition to load your weapons, and in return you help them by making a dent in the monsters' rows. The winner is the player who has killed the most valuable monsters and provided the most ammunitions to their fellow hunters.
