Side-scrolling Shooter Game Online - Intrusion

Rating: 7.9/10 - 12596 votes

Intrusion is a highly-challenging, platform-based, side-scrolling shooter game for older kids where you must blast your way through five levels of enemies including robots, skilled enemy combatants, and helicopters. You play the role of a Rambo-style, stealth commando figure, and must quickly move through tricky platform and ledge-filled levels, eliminating enemies through intense combat, accurate shooting, and generally causing as much mayhem as possible!

Skills required: In this awesome, fast-paced, aiming and accuracy-based action game, you need to exhibit fast reactions and nifty keyboard control skills as you guide your commando through each tricky level. Good observation and hand-eye coordination skills are very important as you try to anticipate enemy attacks, avoid enemy missiles, and survive for as long as possible.

How to Play: A Flash-based, action / survival shooter game for notebook, laptop and desktop PC / Mac (with certain browsers). In each of the 5 progressively-difficult, side-scrolling levels, your goal is to defeat all of the enemy combatants and then the large, airborne Boss character at the end of the level.

Control your Commando character's movement with the Arrow Keys or the WASD Keys on your computer keyboard. Aim using your computer mouse cursor, and Left Click to fire your weapons. You can also fire weapons by pressing Spacebar. Toggle between weapon types by pressing the 1, 2, 3 and 4 Number Keys. If your character is defeated, you re-spawn at the previous Green Flag Checkpoint.

If this Flash-based game no longer works on IE11 or Chrome browser on your PC / MAC, try playing Firefox browser with Adobe Flash player installed.

Before you submit an error report, please review these common issues & solutions:

  • Please use US or Canada based VPN or Proxy service in case you are having a problem with Blocking or Connection Reset. We are currently looking for other reasonable solutions as well.
  • If you see a GAME BLOCKED message or if a game does NOT LOAD in 3-5 minutes even after page refresh - this is not blocked by us. Please speak to school/office administration or your network provider. They are blocking it.
  • If the game DOES not FIT the screen (part of the game area is below above the browser) - see the GO FULL SCREEN button just at the right above the game. This should solve it.
  • Make sure that Javascript is Enabled in your device browser.
  • You may only see a blank screen / or no game screen at all if advertisements are in any way restricted on your browser.
  • Make sure that No Ad Blocker is enabled on your browser (Many game developers only income source is through ads, so they don't make the games available if ads are blocked).
  • Even if your Ad Blocking software is disabled, it may cause an issue with loading an HTML5-based game.
  • You need a High Speed internet connection because some games use large files which take a minute or two to load for the first time.
  • Some games require you to tap/click on the game screen area when they load in order to start.
  • Playing on a different device or browser (with different settings) can often solve the issue.
  • Games are not available in all jurisdictions outside of the USA.
