Delta Force is an oldschool budget tactical shooter franchise and Black Hawk Down is the 6th installment. Team Sabre is a big expansion pack set in Colombia and Iran. The core gameplay stays the same, but the locations and the difficulty has increased.
Same as in BHD. BHD has it's own engine and runs at DirectX8, 4:3 aspect ratio resolution. I managed to get it up to 1200p, it refused to go above. All widescreen solutions stretch / cut off the screen. Considering that it's budget titles made in 2003 the visuals are fine. Decent textures, fine poly count and nice drawing distance (like in every other DF title). Framerate is unlimited. Game is compatible with pretty much all Windows versions.
Considering this is an expansion the mechanics and AI haven't been upgraded and are pretty much the same as in the main game. The only minor complaint is that some objectives are buggy and there are some minor friendly AI bugs.
Just like BHD Team Sabre offers nice background music and nice team dialogues.
With the expansion you get 5 missions set in Colombia and 6 missions set in Iran. Some new weapons have been added. Unlike in the main game these missions are way longer and more difficult (you get less saves too). The shortest mission is around 10 minutes and the longest one is half an hour+. Missions include village, airfield, jungle, island, oil rig, oil pipeline and even stronghold raids with various insertion methods. Some of these mission offer far more complex maps with lots of buildings and enemies which easily makes this far more interesting than the main campaign itself.
If you liked Black Hawk Down then you'll most likely will like this expansion even more.
