So what if Half-Life 2 is out - you're not ready to abandon the original Half-Life yet are you? Not when Spirit of Half-Life is around!
Reissues is a collaborative mapping project that traces its roots back to Project Quantum Leap. The basic idea was to collect a bunch of unrelated maps and short multi-map adventures by authors of all levels of skill, both veterans and newbies, and release it as a single (very incoherent) map-pack. There was no story; each map stood (or fell) on its own. The first Issues was the same idea - in fact it was originally called PQL2 - except that it used Spirit of Half-Life as the basis for its maps.
