Play by your own balanced rules and see how well you hold out or just davy croket em to oblivion, it's gmod after all.

ISSUES and LAG If you're experiencing a lot of lag while playing this map it may be because you have a lot of laggy mods (gore mods, fancy bullet impacts, ai mods, etc) it may also be because your computer is terrible...HOWEVER, inside the "control room" there are some options that can decrease the map's laggy-ness, and a setting that will decrease the max amount of combine soldiers that can spawn. Maybe I will add more "performance options" in the future.

FRIENDLY TURRETS BEING UNFRIENDLY Some people have been having an issue where ally rebel npcs will attack friendly turrets and vice versa, this issue is caused by mods, most commonly by INPC. You can disable INPC, or tweak its "faction control" option, which should also fix the problem.

Features: - open battlefield - procedural waves - difficulty presets - Trenches - bunkers - turrets - gun emplacements - navmesh - "funky" "mine layers" - goofy ass "tanks" - artillery - lots of rockets - striders - gunships - "the Bricker" - supply spawns - friendly rebels - lots of combine - chaos - lag

Let me know if you encounter any issues or have any suggestions!

yap: yeah so i wanted a PVE map that felt more like a battle (or just a different kind of battle) with a largish open area and a clear defensive line. I think I may have spent years making this shit because I kept getting bored and abandoning the map or restarting from scratch. Usually I'd come back to it a year later and have to use 200% of my brain just to understand what the FUCK I was doing.

visual mods in some of the screenshots: - vFire - zippy's gore mod - zippy's impact effects - Explosion Effect (this makes the tanks die weird btw [no fucking idea why]) - Bullet Tracer Effects (HL2:MMOD)

have fun and stay safe please
