Alien Shooter: Revisted is an updated version of Alien Shooter. It has been ported to an engine that looks very similar to Alien Shooter 2, and comes with all the improvements you might expect from that process. Some of the flaws that haunt the original game still appear in this one, however.
Like you would expect, Alien Shooter: Revisted involves shooting lots of aliens, and that may be an understatement. On some levels your kill count will be up in the thousands. You control with WASD and shoot with the mouse, holding down the left button to shoot and using the cursor to aim.
The style of this game is an isometric top down shooter. I found that the isometric view could actually be a hindrance at times, with many enemies being hidden along the wall. You will find yourself being injured by aliens that you could not possibly see, and I have a slight problem with that.
The graphics have been drastically improved from the last version, and some light RPG elements have been added. You can purchase upgrades to your skills or weaponry, however a lot of weaponry can be found in the open throughout the levels. The enemies and characters have some additional detail over the original, and the environments have been give a new coat of paint. This looks more like a commercial title and less like a free flash game that the original did.
The game still lacks voice acting or much of a story. You just kind of dive in to the scenario, committing genocide without much thought. With Alien Shooter 2 having much more story going on, it makes its absence well missed in this game.
While Alien Shooter: Revisted has welcome improvements over the original, it is still missing too much to warrant much of your time. Without much of a story going on, and the upgrade elements still feeling a little too light, I would skip this in favor of Alien Shooter 2: Reloaded or another shooter.
