******* NOTE: On the Desura page, please be sure to download 'Full Tactical-Expansion V1.1 Installer", as this will eliminate the Desura installation issues. ******* This mod enhances the things that make Crysis great, and adds a number of new things. New blood effects, bullet drop and penetration, 22 new ammo types, and more weapon changes than I could list here. Armored vehicle have different ammo types. The US Tank gets SABOT, HEAT, and Canister shells. The NK Tank gets HEAT, SABOT, and AT-11 Missiles. The APC's get HEI-T (normal) shells and Canister shells for the cannon, and the TOW missiles are now player guided. Weapons are more versatile, for example the Gauss Rifle can destroy any vehicle and can shoot through concrete walls. The SCAR with all the different attachments and 40mm grenade types can be used in any situation. Also included are Fortran's Barrett M107, and Rad15's advanced AI, used with permission of the respective creators.

phenomenal overhaul! I fell in love with it as soon as I shot the first KPA on the first level. and it just kept getting better from there on out

Pros:
much higher weapon damage. they feel similar to Battlefield 3 campaign.
outstanding weapon models and textures to all added weapons.
Bullet drop.
LOTS of useful attachments for the SCAR.
6 levels of magnification to sniper scope and binoculars
Cross hairs on sniper scope are actually good! they don't float around like vanilla Crysis.
Extended battery life on night vision.
more ammo for the SCAR and can sometimes be picked up in game when friendlies (dead or alive) are not around, so I can actually use it and not worry about running out.
realistic weapon damage to vehicles. particularly with the M107 shooting an engine block out.
Smarter AI.
better weapon sounds.

Cons:

sound from the FY-71 is too loud.
a little glitchy when coming out of ADS on custom weapons.

neither of these things are game breaking, in fact the glitches are almost not noticeable and so I have decided to not mark down for them.
