Welcome to Halo 2: Ultimate Campaign Tweaks!

This version of the mod is out of date. Click here for the new update.

Do you want to replay Halo 2 again in a whole new way? Do you wish Bungie had just one more week to add some finishing tweaks to the campaign? Do you wish more missions in Halo felt like Assault on the Control Room from Halo: CE? If so, then this is the mod for you. The basic premise behind this mod is that Halo 2 didn't have enough allied A.I. and this is particularly obvious on higher difficulties. This mod uses the existing framework of the campaign to try to add a diverse range of new allied A.I. whilst also keeping the missions balanced. In the original game, the player would receive a small fireteam in most levels and, once they were all dead, a handful of allied A.I. would arrive to replace them. This mod enhances that idea by supplying the player with a lot of A.I. allies at the start of the level and enhancing the various A.I. drops so that the player is less likely to end up in situations where their allies have been totally wiped out. Now, your allies can take acceptable losses and you can still push on with a complete fireteam, and if you manage to keep your allies alive, you will be rewarded by having large squads in various points throughout the campaign, just like how Assault on the Control Room in Halo: CE functioned. Read a list of changes below, though is this is just a brief overview as there are many surprises throughout this mod.

There are also several alternate versions of certain missions in the Optional Files section that change up the allies, usually adding Covenant allies to Chief missions amongst other things.
