Hello, in the last few days i have been working on making a survival map as the rebels. You have to survive as long as you can while wave after wave of zombies attack you. i have made three map attempts and though all could have been succesfull but ive put most of my effort into this one. This map is hlw_ZomDefence_2, it features a good-sized fortified building to defend. a decent-sized Roadblock/Combine Outpost, and a small building which some combine soldiers have been trapped in. -Currently the Combine will not bother to attack your men, as they are to focused on eradicating the zombies, yet only a small amount of combine will bother to use their ammuntion on the zombies because they do not have the means to attack the combine. (2 Sniper combine and trapped combine soldiers will of course fight. You have about 12 Rebels (including 2 medics) with different weapons. 2 Setup Machine guns covering the North and South of your building are at your disposal. Fight for as long as you can.
