Halfway is a horror/survival/tactical squad combat game that is part Aliens, part XCOM lite. The plot is simple enough... You are aboard the colony ship on a journey to another planet when you were awakened in a dark ship, signs of combat everywhere, nobody around. What is going on? What happened to the crew of thousands? As you explore the ship, you encounter / rescue other survivors, each with some special abilities, and enemies that seem to have taken over the ship. Can you figure out what is going on, and find a way to get out alive?
The game is drawn in an 2D view with a complete cover system, and the somewhat low-res look is retro-ish and rather charming without overly distracting. The game lets you walk around in "real-time" until enemies are encountered, then it becomes a turn-based game where you and enemy alternate turns, all of his units vs. all of yours. You will also have to rummage through containers looking for supplies, such as health kits, shield rechargers, better weapons, and grenades. Occasionally you'll run into hypos that will enhance your stats. Each character has 3 stats: health, agility, and aim. Health is your hitpoints, agility is how far you can move per turn, and aim is how well you aim your weapon.
Combat is simple: each character has 2 action points per turn. It can be spent on shooting, moving, or misc actions such as "use medpack", "reload weapon", and so on. If you have no visible target you can also set your guy to "retaliate", which means s/he will shoot at any enemies that fired on him/her during the enemy turn, but only once. You can mix actions, like shoot then move, move then reload, and so on, or just make a long-distance dash. There is no "reaction fire" or initiative in this game, only retaliation fire, which can be somewhat frustrating to veteran players of other turn-based tactical games. But once you get used to the mechanic it works just fine.
There are multiple types of enemies as you advance through the plot, and the difficulty starts ramping up, but you also get better weapons to compensate. The simple Mk I weapons don't do that much damage, but are adequate against the weak enemies you encounter. By endgame you have to wield Mk III weapons that do much more damage. you also encounter armor that initially provide little protection, but by endgame you'll encounter Mk V or even Mk VI armor that provides tremendous protection, but enemies can do a lot of damage as well, and is heavily protected.
Cover mechanic is very important, as a "full cover" imposes a -30% to-hit penalty on enemy shots, and that can be significant. Half cover only gives enemy a 15% penalty.
Your armor can reduce incoming damage as well as outright absorb damage with its built-in shielding. The shield automatically recharges after a few turns, and if you can't wait that long you can use a shield recharge pack to recharge it at expense of 1 action point. They come on small (5 pt), medium (10 pt) or large (20 pt) sizes. Similarly, medpacks, also comes in small / 5, medium / 10, or large /20 sizes except they heal your HP.
Each character also comes with a special ability. One guy has a "radar" that can reveal all bad guys on the map (obviously that's moot the next turn, but it's good to have an idea). One can paralyze an enemy for several turns. Another can overload an enemy's shield (i.e. no shield for X turns). Yet another can teleport. To win the battle you will need to figure how how best to deploy the assets that you have, be it grenades, armor, weapons, but also the special skills of each member of the team. Usually you can only deploy 4 members out of 8, so choosing whom to bring and how to equip them is a major consideration.
Fortunately, as mentioned before, you are welcome to search the boxes for supplies. You can also recycle anything you no longer need (like obsolete weapons and armor) so you can use the energy to synthesize stuff that you do need. Killing bad guys also yields additional energy.
The enemies in this game have different tactics. Some dance at a distance, some rush, but all are nasty.
If one of your team members had fallen in combat, don't worry just yet. If you can defeat the current batch of enemies, the member will recover (with 1 HP) at conclusion of that combat phase. However, keep in mind that each mission can have multiple combat phases.
As you explore the ship, you can go on "side missions" which will yield additional loot, and adds to the background of each character.
Having completed the campaign, I'd say I enjoyed this game quite a bit. It is occasionally frustrating, but usually due to my poor tactical sense or lack of preparation (bringing the wrong team members or wrong equipment). If you like the tactical turn-based combat genre, you should give this game a try.
