Well, Invasion From Mars is the newest multiplayer Half-Life mod in town (as far as I know) and to kick things off, here's a little info:
Invasion From Mars is a Half-Life comical multiplayer mod based on movies like Mars Attacks! The mod puts players as either a Martian or an Earthling. Each with different and contrasting weapons, abilities, and characteristics.
Also, Invasion From Mars' newest team member, Maleficus, has already served up a render for the Pump Shotgun which will be used by the hick character called: Mary Lu, who used to be Hubert but Ferret and I decided we needed a female.
Here's the render.
Lastly, Invasion From Mars has a custom logo up here at moddb so enjoy it and comment on it. Peace.
