Still no complete package or news post...
Asaki's mod: Not really a Halo vibe, but the modification to the weapon system was good. Could have been any other modern realism shooter. I didn't like the map - guess it should have been textured in some bland grey theme. Also, I missed AI-driven vehicles that bump into every possible obstacle.
Supa's mod: Nice idea. Took me a while to figure it out. I liked the tactical potential, even though E1M1 is probably the wrong map for that kind of game mode as it's 100% linear. I could imagine this to work better on some of the DM maps. Do defending monsters infight?
This might even make for an interesting multiplayer game where two players or even two teams with several players play against each other. The one who manages to get their monsters through to the other team's exit wins. With a player responsible for the defense and another one for the attack. Or something like that...
