Thx.
Some of the more significant updates/differences:
All 'weapon' specific perks such as bullet damage have been moved to a separate weapon enhancement section that works as a second attachment of sorts. The first is an actual attachment (acog etc) while the other improves performance.
That in turn opened up 7 perk slots. Some of which are used for splitting up a few perks, to allow for a little more specialization, and adding some others. Yup includes marty. Drops a standard semtex so it flashes and beeps. Hey its not so bad. Scorestreaks. Three primaries/secondaries. The first weapon you pick up from a dead player is added and does not replace the one you are holding. Scavenger, and subsequent pickups, work normally with all three.
Various weapon replacements. A third assault class special. A sniper special. GL attachment restored (M32 inventory option removed). Explosive crossbow only and impact explode (to deal with an unforseen issue). 6 rounds, however compared to the 2-round smaw/rpg its power and radius is limited. 2 mags of 3 rounds each.
Reaper removed (incompatibility with cod4x and player guided missiles). However the ac130 restored, which imo is a much better streak. Needs real world testing, so to speak, to make sure it looks good or at least reasonable for weapon fire. The plane is significantly farther away with a little sleight of hand for the player/owner. It seems to be the way the designers were going to handle a potential ac130 streak in an early version of the original game. It requires SAMs to destroy it.
Additional super character, for two. Duke and Ghost. Each serves a different purpose and choose the one that best fits your needs and location. Slow but heavily armed... minigun and rockets... and armored. Or fast with light weapons, good health, but no armor.
Multi-mine streak. Places an item that has four bouncing betties. This is similar to the IMS but went with something different that affects everyone and everything 360, exploding cars for example, not just a pulse beam.
A lot of various behind-the-scenes improvements meant to improve game play. Havent been able to test all of them but compatible with all stock games and ctf. Uses standard/original server settings.
