Contingency mod for Half-Life 2

Background

Kill as many waves of enemies as you can with friends online, or take the fight alone. You are a squad of rebels five that need to eliminate as many aliens and zombies as you can. This is a suicide mission and you know it, but why not kick some ass before dying. The game is set in the universe of Half-Life 2.

Gameplay

There are waves of enemies coming to take you to hell. The squad has to survive by killing the enemies with various weapons. By killing enemies you will gain credits, which you can use to buy props. During each wave there will be a certain time limit, depending on the map, where you can prepare yourself for the next wave. In this time you can use your credits to but props (every prop has a different health and costs) in order to block the enemies way, like walls and wooden planks. If you die during a wave you will be respawned if your squad survives it. In Singleplayer you will be supported by four civilians that help you fight the hordes. In Multiplayer the waves will get harder the more people join (maximum of five players).

Weapons

At the beginning and between the waves you are able to change your loadout. The loadout consists of your weapons and tools. To be exact you will have a primary weapon, secondary weapon, tertiary weapon and a special weapon or tool. But be careful, every map is different, there you might want to adjust the loadout.

Enemies

There will be waves of zombies, combines and antlions. Each and every wave will be different as there is various types of different zombies, combines and antlions. Moreover there might be only one type of enemy in one wave and a mixture of them in the next wave. But zombies, combines and antlions do not mix.
