Slipgate Classic Beta 1.1: Quake's campaign rebuilt on the Half-Life engine

Slipgate Classic Beta 1.1 is out. It's Quake's campaign rebuilt in GoldSrc with more Deathmatch Classic flavor: DMC weapons, items and armor, while the enemies still fight like Quake. New: widescreen FOV and weapon pull-back options, Quake-accurate shotguns, a third-person end-of-level camera, smarter monsters, bots and Find Servers. Requires your own copy of Quake plus Half-Life and Deathmatch Classic on Steam.

Beta 1.1 changelog:
- Setup builds the music, sounds, textures, HUD and skies from your own Quake install. Run setup.bat in the SGClassic folder once.
- New options: widescreen FOV (set it in Options before loading a map), weapon pull-back and Fast Switch
- Shotgun and Super Shotgun damage now match Quake
- Third-person camera at the end-of-level stats screen
- Monsters stop at ledges and chase more like they do in Quake
- Bots, with a menu to pick which bot to remove
- Find Servers: hosted games show in the server list
- Fixes to secrets, E4 pickups, keybinds and the menu music
