I like Phoenix because it introduces new weapons. I'd like if it were easier to complete the levels and not so easy to get lost and end up having to resort to the map.
A 35-level single player major conversion.
This scenario is difficult and action-packed; it features a full arsenal of new, powerful weapons, and more threatening enemies than you could ever want.
1.4 has new Lua features like a performance overlay, weapon buffs, a lot of little bug fixes; it also applies ammo capacity limits on Total Carnage. Requires Aleph One 1.5 or newer, probably!
