Contra is a freeware modification for Command and Conquer Generals: Zero Hour real-time strategy game. It's a big project started in 2004. It adds many new units as well as numerous new upgrades, new general's powers and buildings. It also adds new sounds, maps, bug fixes, enhanced graphics, and other effects, as well as three new generals.


  • Introduced Ranking system, in which that certain buildings and units can only be built when a certain general's rank is achieved. Players get awarded for their combat efficiency.
  • 3 New Generals - USA Cybernetic, China Flame and GLA Assault.
  • A.I. is greatly enhanced.
  • Introduction of "Super Units". The limit is 1 per player (like hero units). Super units require 5th rank. Each general has a unique super unit.
  • Neutral Tech Structures reappear after a while after they are destroyed.
  • Deep variety of gameplay tactics and strategies.
  • Wide choice of units, buildings, special powers and upgrades.
  • New graphics and sounds.
  • All 12 generals were made as diverse as possible. The gameplay for each general is unique.
  • Simplified micro management (since Contra 008).
  • Each faction speaks its own language (since Contra 008).
  • Increased stability in multiplayer games (since Contra 008).

USA Generals:

Air Force - Malcolm "Ace" Granger

Air Force general depends on speed and precision. He requires skillful
control and is heavy on micro management. While being a powerful general
the skill and experience required makes him difficult for many
beginners to play.

Laser - "Pinpoint" Townes

Laser is a versatile general strong in call situations. He is flexible and has
units to fill every combat role. As a result he has no weaknesses other
than being a specialist at nothing.

Super Weapon - Alexis Alexander

Advantage of this general is easy micro and very simple strategy. Almost the same
vs all enemies - build up around enemy until he dies. However, you
should not ignore other abilities.

Cybernetic - Algrin "A.I." Ironhand

The generic feature of this general is his mobility, which allows to move
an entire army very fast and create numerical superiority at desired
areas of the battlefield. His basic strategy is unstoppable maneuvering
along enemy base perimeter. If he finds a weak point in defense, he
moves there instantly and destroys the most significant targets.

China Generals:

Nuke - Tsing Shi Tao

Nuke General must rely on aggression to defend his base. He has no defenses
to hide behind while you wait for your nukes to load. The absence of
defense structures forces the player to be more active and aggressive.
Use your units to carry out counterattacks for defense and support your
main attack with super weapons.

Infantry - "Anvil" Shin Fai

Infantry is a volatile general given to decisive victories or defeats in the
early game. As expected, he relies on masses of infantry in the early
game, later reinforced by more infantry. In the late game he gains
powerful artillery strikes supported by the same infantry.

Tank - Ta Hun Kwai

His strategy is easy to understand, but not as easy to implement:
build more tanks and attack. But everything has its details.

Flame - Huang Lin Bao

He has the same strategy as tank general, but another means for its
implementation and another battle tactics. His vehicles are not as
armoured as tank general's ones, so he has to use artillery and
different tactics and tricks, instead of forcing his way through.

GLA Generals:

Toxin - Dr. Thrax

Toxin General specializes in area attacks and damage over time. He is
especially effective vs mobbed units and hordes. If well played, you
will find all of your positions unapproachable for the fields of acid
and poison.

Demolition - Rodall "Demo" Juhziz

He is a versatile and powerful general with demanding micro management needs.
Since almost all units are disposable, you must use them with care,
directing almost all kamikazes manually. The more assiduously you play -
the more complex it becomes for enemy to defend from your endless flows
of kamikazes. If you play properly, you can defeat any other general.

Stealth - Prince Kassad

While at a glance his units are weak and poorly suited of combat, Stealth
General is a deceptively powerful general using infiltration and
surprise to his advantage. He has long range sniper units capable of
attacking with impunity against units lacking stealth detection. He is a
challenging general to play, but has a strong reward for the effort given.

Assault - Mahmud al Huchum

Assault is a flexible general with flexible units. He requires low micro
management and is well suited for most players. While having
no spectacular abilities he also has no weaknesses.

Hi everyone!

This time, we made a special treat for all of you. Before showing renders with descriptions as usual, we put a bit more effort and made little trailer video about this update.


Holding onto something while watching video is highly recommended, due to much awesomeness which causes your ass falling on the ground!

Now, let's explain what we saw.

- first, there is a new cool thing for Laser general. His Power Plant structures got unique upgrade, Laser Fences which can be upgraded from rank1. Laser fences will protect Power Plants from sabotage, and capturing by killing any infantry which comes very close. It also provides additional health to structure. But upgrade is not cheap, and drains one power point.

cores render

- defense cores are special vehicle units for Super Weapon general, which can be produced from Command Center. From left to the right, Patriot, Ion and Grendel. As we saw in video, they can be deployed in their respective defense structures. Their cost is equal to defense structure and half of the Dozer price. In balance order, they are vulnerable, and especially in deploying phase which takes around 7 seconds. Defense cores are great at reducing micro, and capturing more zones on map. Carrying them by Chinook and deploying multiple at the same time, is much easier than building each structure with one Dozer.

- Atlas defense structure is already shown:
Atlas defense
And now you saw it in game, with new weapon projectiles.

weather render

- Weather manipulation device, is actually replacement for Blackout Missile System. More or less, it acts the same, but more visual effect is given, and will be even more. It also deals a bit more damage.

- Thing which is not shown in video, is Gatling addon for Patria
gatling render

In order to balance Infantry vs. Airforce matchup, minigun upgrade for minigunners is moved to rank 3, while Gatling upgrade affects Machinegun Patria both visually and with firepower.

And last but not least, is visual improvement on all USA structures, thanks to PredatorBG who took some time and effort to improve them for all of us


We would also like to thank Hecthor Doomhammer who gave great review of Contra mod.

That's it for this update, see you soon!

so far i have beat the challenge on medium with stealth, robo and nuke gen, and on hard with SW and laser gen.

just wanted to give some feedback about the gen challenge. ( this is just what i have experienced so far, others may see something different)

1.demo gen is harder on medium than on hard imo. on medium he keeps building aircraft's that loves to snipe my dozers/workers in the early game. on hard he builds 1 maybe 2 and thats it. all other attack scripts seems to be the same. it does appear that hes first attack comes sooner on hard though.

2.stealth gen does not capture tech buildings such as the oil derrick's, so hes attacks quickly fall in strength, especially after he has mined the supply in hes southern base and all that gives him money is 2 black markets. destroying hes north command center seems to trigger a money script and suddenly he starts building units nonstop.

3.was playing as laser vs tank gen on hard ( this was a fun one ) at some point, after i had destroyed all hes super tanks, i flew a lone aurora bomber near hes base and he got ******. all the 60-100 tanks in hes base started to move directly at my command center! it had me scramble to get everything lined up to stop them hehe. not sure if that is intended though.

4.terror gen stops attacking after a point as more and more units get "stuck" in hes base and he slowly reaches his "build limit" if you wait long enough, there will only be a few toxin tractors attacking.

5.infantry gen's aircraft fly in circles in the upper left corner of the map. on my hard play through as laser i did not get attacked once by hes aircraft's.

other than that, this challenge is great fun. i will try to do the challenge with all generals whenever i get time for it.

keep up the good work.

1. I checked demo plane teams. Nothing indicates that they are harder on Medium than on Hard. However, some teams are set to produce random amounts of units (for ex. Doplhin (anti-ground demo plane) teams on Easy/Normal/Hard consist of 1-2/1-3/2-4 team members. It is possible that you randomly faced more Doplhins on Medium than on Hard. I'll make them less random now.

2. Stealth AI will be strengthened.

3. Yes, Kwai often gets ****** and it's intentional.

4. I'm trying to fix this one.

5. Planes flying in circles in the corner is a known glitch.

alright. i kinda wish i knew more about scripting the AI and stuff so i could potentially help out. all i know is how to edit INI files for more camera zoom out, remove camera shake and extend vision of an area before the fog of war returns.

anyways, keep up the good work.

Hi there, is there any way to watch high skilled players play against each other? with or without commentary.

to think i only install this recently although i already know it 5 years ago..

First, great work guys! i really love the Airplane selection on right panel, really helps me when using my fav Gen."Ace".
But somehow the general challenge is a bit unbalanced, (i can complete it in Medium using Gen. Ace, but not with any Chinese Gen.(in medium)) especially against Dr thrax.. poison with camo infantry at start ? oh come on..

Good suggestion. Rebel camouflage will be moved to rank 3.

Reply Good karma+1 vote

thx for replying.
also have you tested the general challenge in Medium in latest patch? the timing of first enemy attack a bit too fast. while in other (ex: Gen "Algrin") a bit too lenient

Attacks are fine. You need a few tanks to stop the first waves. As China, a bunker early on helps a lot. Challenge against Ironhand was broken (he almost never attacked).
